Wal-Mart Fertilizer has no phosphorus anymore.
Comments (24)There is a huge 'dead zone' in the Gulf of Mexico. Do you really believe that it is caused by homeowners using too much fertilizer? I don't. The dead zone is blamed on runoff from farmland. If farm runoff is enough to cause that dead zone, how can it not be the cause of Phosphorus in streams and water supplies? When farmers farm, they do a very carefully analysis of how much fertilizer they need to maximize their profits. If they don't, they go out of business. They could care less about runoff if their farm is at stake. I agree with cyrus on this one; it's political. Just as with air pollution and vehicle pollution controls, it is politically expedient to force the ordinary person to bear the brunt of regulation. Businesses get a pass. For years, trucks were exempted from the requirement to use catalytic converters. They were 10% of vehicles on the road but they were creating 50% of the air pollution. Only recently were they required to clean up their exhaust....See MoreGreen Manure For Food !
Comments (2)I'm sorry I forgot to say what's in the mixes. In the first picture for FALL: This mix is comprised of winter rye, field peas, ryegrass, crimson clover and hairy vetch. Vigorous late summer growth provides winter erosion control. The peas, clover and ryegrass will winter kill to provide organic matter and soil cover. The hairy vetch and winter rye will regrow in the spring to provide nutrients for crops to utilize. For the Spring Mix , in the second picture: Use as a green manure to enrich the garden with both nitrogen and organic matter. The mix contains 60% field peas, 25% oats, and 15% hairy vetch. Designed for spring sowing, but it may be sown anytime early spring through late summer. Our backyard is part of the Rocky Mountain , literally! And so to tame patches of it, since it is not level, our son weed-whacked the rag weeds and other unwanted last fall, and since my Fall mix didn't arrive until too late(didn't want it all eaten by the wild pheasants and other wild residents-might have to pellet the seeds with fine clay powder because of that), I will sow the Spring mix very early on patches maybe 10x20's on the South facing incline for additonal gardening places and let the mix do the weeding out and the fertilizing and the softening of the dirt, and the composting, to get them ready for vegetables and flowers for the year after. I am planning to always have a patch of the mixes growing for seeds, and to rotate them from one patch to the other, and intersperse their plantings with my regulars when ever possible. Bon, bref, I've been long winded,as usual. Chris...See MorePotassium excess & poultry manure application
Comments (13)Peter- Do you have a handle on number that would be considered problematic? Maybe a number that even if row crops were planted in with cover crop following that wouldn't be able to take back down to borderline high/excessive? What you say is encouraging, but I'd really like to know some sort of ranges before I make my decision. Note that too much K will doubtful become a problem around here. The challenge ( I believe) is always going to be P because of the ratio in my manure and it's inclination to stay put. Thanks! Kimmsr- To a degree, I understand how excess P affects the availability of other nutrients.... although only a superficial understanding. So yes, I agree that too much P is not a good thing. That being said, I do not have a handle on the numbers that are considered excessive and where in the excessive range things start to get out of whack. Also, don't know if the P range from Low to Excessive is a linear range or Logarithmic (?) (meaning that for all practical purposes just the excessive range could be between 120 (which it is in this case & 5000 (which I highly doubt), but the fact that excessive is at the end of the range complicates things because it's unlimited. Just want to know how much my addition of 130lbs moves the bar into the excessive range. Note that my water is on a well, so yes the excess P levels concern me. That being said, if my well water is going to get contaminated it's probably from all the farm land around me rather than my relatively insignificant tract. All that aside, I still want to do "the right thing", just want to be smart about it. Note that the only way that the P levels could have gotten this high in the first place (assuming they are this high) is because of the synthetic fertilizers I added last year. Anyway, I'm trying to come up with a system now that is sustainable from my point of view and I'm attempting to start now rather than later. Thus trying to avoid adding more synthetics when possible. Meaning, they got me into this mess in the first place. I have a composting experiment going right now with the chicken manure just not sure how it's going to work. Chicken manure and pinestraw..... yeah, I know not ideal but it's what I use for bedding because I live on pinelands and it's readily available and free. Just not sure how it's going to compost. If it works, I'll be more inclined to compost. If not, less inclined to do so. That being said, I have 3 or so acres planted in oat/clover cover crops right now that I could use to make compost later- a possibility. But, that "requires" more implements/labor etc than rotating out cover crops with cash crops. Bottom line is it's more efficient for me to come up with a method that I don't HAVE to compost, especially since I have my poultry manure available. To answer your question about humus level, right now it's pretty limited and it's sand loam (mostly sand), so yes leaching is a problem. I'm steadily building the soil with cover crops and mulch but still have work to do. Thanks!...See MoreWhat are the Benefits of Cover Crops or Green Manures?
Comments (0)Cover crops and green manures are basically the same term. When these plants are alive they are cover crops. When the plants are decaying they are green manures. Green manuring has all the soil benefits of classic composting, plus other benefits: 1. Green manures can fertilize large acres of land cheaper and easier than hauling in tons of finished compost. 2. You can eat the produce of certain cover crops like beans, peas, or radishes. It is harmful to humans to eat compost! 3. The roots of certain legume green manures can supply tons of free atmospheric nitrogen per acre to the topsoil after the cover crop plants are tilled, mowed down, or smothered. Rhizobacteria live inside the legume roots creating a unique relationship that actually converts atmospheric nitrogen into organic nitrogen for the legume to use. This extra nitrogen fixation built up by the rhizobacteria can not be beneficial to other plants near by, or future crops in the soil next season, until that legume is dead and recycled into the soil by the green manuring process. Compost can't fix nitrogen in the soil. 4. All green manures supply extra organic matter to feed and breed beneficial soil organisms for soil fertility and soil health. 5. The roots of certain cover crops can go down several feet below the topsoil and into the subsoil to break up hardpan and pull essential nutrients up to the topsoil level at green manuring time. After 24 months of continuous growth, alfalfa roots can extent over 20 feet down, that can turn it extra OM down into the subsoil! No regular tractor or mechanical tiller can plow that deep! Without tilling it in, compost can't do that. 6. Some cover crops can weed out other plants. Buckwheat, oats, and sunflowers are good types of these allelopathic plants. 7. Some cover crops can attract beneficial insects and repel bad insects like marigolds and crimson clover. Compost can't do that either. 8. Some special cover crops can help control diseases in the soil or on the foliage of nearby plants. Examples are garlic, onions, hot peppers, basil, marigolds, thyme, and other herbs. These plants can protect plants like tomatos from diseases. They can also control bad nematodes or other soil problems. Some of these cover crops can do these functions as living plants or as decaying green manures. 9. Some legume cover crops, like white clover, can be planted next to your crops during the warm season to be used as a living mulch. 10. Green manures work best when mixed with legumes and non-legumes. That way you get the nitrogen fixing benefit from the legumes, but also you maximize the fast growth of the expansive root development and tall foliage height that is characteristic of grasses and grains. 11. Did you know that about 95% of all the bulk and biomass of all non-legume cover crops is a direct production from only water and photosynthesis! The other 5% is straight from the soil. Legume cover crops go farther and pull free nitrogen from the air also. That means that all cover crops will add more humus to the soil than what was there before just from energy from the sun and the atmosphere. Since humus is mostly carbon, hydrogen, and oxygen from the air, that means that cover crops greatly benefit the biosphere and the soil microherd, just from above! Plain compost can't do that! ******************************************************************************** Green Manures have other nicknames also beside Cover Crops. Sometimes they are referred to as Smother Crops, Catch Crops, Nurse Crops, Living Mulches, or Compost Crops. Green manures also help conserve nutrients from the topsoil and even the subsoil, in bad weather, varying temperatures or seasons or climates. Green manures help solve crop rotation issues for small or large garden spaces. Green manures can even help heal soil diseases. Green manures can help buffer soil pH with its organic matter in the soil just like compost for the next planting season. Green manures are also great at controlling erosion and soil water moisture content. A nurse crop is a fast growing cover crop like rye that is grown close to a slower legume cover crop like hairy vetch in order to help support the plant's foliage as it grows. You can grow a cover crop in order to supply green nitrogen rich organic matter for your compost bins. Next to classic composting, green manuring is the greatest single thing you can ever do improve your soil and your gardening environment. ******************************************************************************** Mostly all cover crops can be grown easier by sprinking or lightly covering seeds on top of 1-2" finished compost or rich garden soil. This a partial list of some of our favorite cool season and warm season cover crops and their basic purposes: A. Crimson clover - cool season annual legume. More cold hardy than most other clovers. Grows great on all soil types in 1-2 months. Supplies lots of foliage and roots OM. Crimson clover and winter peas can be found in deer plot mixes. Attracts lots of beneficial insects. Easy to green manure. The favorite legume green manure of the south. B. Hairy vetch - cool season annual legume. It is the most cold hardy of the popular legumes. Can grow in temps below -5 degrees F. Can be found in some deer plot mixes. Great legume weed suppressor. Grows great with a non-legume like rye as a nurse crop. The favorite legume green manure of the north. C. Rye, winter wheat, and oats - cool season fast growing grass/grain non-legumes. Rye is the most cold hardy of all green manures, and it can grow almost anywhere. Rye can grow in temps below -20 degrees F. Rye and oats are a great non-legume weed suppressors. These crops can grow fast in a few weeks. Supplies lots of OM. Rye must be killed at least 4-6 weeks before planting spring crops to not hinder seed germination. You can find these cover crops in deer plot mix or horse or cattle feeds. D. All beans and peas (legumes) - All beans are warm season except fava beans. Most peas are cool season. The most cold hardy peas are winter peas. Most dry beans and peas sold in bags in grocery stores will sprout and grow fine. E. Radishes, mustard greens, rape, kale - Great cheap fast growing cool season annual non-legumes for lots of foliage OM. A thick crop of mustard, rape, or kale is a great non-legume weed suppressor. a thick crop of radishes are great for repelling many bug pests all year round. F. Buckwheat and sunflowers - Great fast growing warm season annual non-legumes that can break up hardpan, kill weeds, and pull up insoluble subsoil phosphorus from minerals up to the topsoil to make available for next crops. Buckwheat can grow fast on any soil type (4-6 weeks to maturity). G. Marigolds and other herbs - warm season annual non-legumes. Marigolds when planted thick, it's great for nematode control and other pest controls. Garlic, onions, and hot peppers control many soil pests. H. All weeds - This unknown class of green manures recycle much needed foliage and root OM and nutrients back to the topsoil. All cover crops should be either tilled in, mowed down almost to the ground, or smothered by organic mulches before they go to seed, to prevent sprouting later in the year and becoming a weed themselves. The no-tilling option is the best way to get optimal soil health, texture, and soil microbial activity. Recent research has proven that excessive tilling, or tilling too deep, can kill off beneficial fungi in the soil and create soil texture problems and some soil fertility issues. If you decide to go with a no-till garden, you can poke holes in the soil around crop roots with your spade fork, to get more oxygen in the soil to further increase organic matter decomposition and increase microbial activity in the soil. Year round green manuring practices can not only improve your soil health and texture, but also decrease extra periodic plant fertilizers and soil amendments.
