A soil test may sometimes reveal that you have too much of a certain nutrient or mineral in the soil . Sometimes you ’ll even discover instruction to pull out them , whether it ’s using piddle and gypsum to leaching atomic number 11 or sawdust to draw out nitrogen . But how is this done , and are there choice to using the chemical substance fertilizers urge when it comes to balance those nutrients ? Thankfully , the answers are yes and yes . If you ’re a beginning farmer in need of soil balance , here are some techniques for refill the nutrient load .
1. Leaching
Leaching is the remotion or loss of soluble nutrients through the coating of water , either naturally from rain or by design through irrigation . It ’s most commonly associate with the depletion of atomic number 7 in commercial farming situations ; however , if you live in an arid environment , you could have a surplus of sodium in your soil that a soil test may hint you leach out .
When leaching salt , it ’s often advocate that you mingle sulfur or gypsum into the grunge first , then several weeks later carry three or more inches of water over the same grunge . This process will indeed percolate the sodium , but it might not be the dependable enjoyment of H2O — something arid environments are lack — unless you have access to a pool . or else , consider mixing in the gypsum or sulfur before the rainy time of year , and permit the rainwater leach the sodium for you . Or you could jump the leach entirely and move to suggestion No . 2 .
2. Cover Crops
Cover crop are swell things . you’re able to apply them to retain valuable soluble nutrients or to remove ones in overindulgence . For example , if choosing not to leach excess sodium , you could mature mustards or barley , both of which can wield the high sodium and will also suck it up . Once the crop has acquire and while it ’s still lush , you could dispatch the plant issue from the subject area to a disjoined compost pile ( as to not after bring the nutrient back to the ground ) or to a Na - deficient plot of ground .
Of naturally , utilizing cover crops in this way should not be limited to just sodium . clean a cover charge craw that enjoys your spare nutrient , implant it , remove the growth and , with it , the excess nutrient . Alternatively , deal growing something comestible with those excess nutrients .
3. Crop Selection
Let ’s say your dirt test descend back high up in nitrogen . In this case , you have several option for removal : you’re able to let it strip out over the wintertime or cover harvest the plot , but nitrogen is a valuable nutrient and should be preserved however possible . That ’s why perhaps the respectable option is to simply grow a harvest that could take reward of the supernumerary nutrient , such as corn for high N , capsicum pepper plant or melons for eminent phosphorous , or peanuts or alfalfa for gamy K . The crop will effectively suck up the extra nutrients and turn it into food . For adept output , add fledged compost to the planting surface area first .
If you are hope to retain nutrient in the soil over wintertime , you could sow daikon radishes , aka vegetable oil - seed radishes , which will not only break up compression but hold those nutrients over until the next uprise season . Even if you have redundant food , this might not be a bad idea because you’re able to always tot up the deficient nutrients to rebalance the ground in the new year . When planting daikons , add some organic topic to balance the soil , then impart compost before planting the next sequent harvest .
4. Rotational Grazing
ruminant — goats , sheep , cattle , et cetera — are peculiar kinds of lawnmowers that efficiently commute pasturage into manure . With a little use , they can deposit that manure wherever you take it . If a soil test depict an supernumerary nutrient , some farmers quickly browse that grass before proceed them onto a substandard part of the pasture . This activity is call rotational shaving . If the stock are n’t run off the ground with the excess nutrients , they ’ll simply stick the food right back onto the dry land and into the soil .
5. Mulch
In order for most mulches — particularly those made from sawdust or soft wood — to break down , they want nitrogen . So the mulch takes that N from the stain before it start out its decomposition reaction . If you leave the mulch there , it would eventually break down and become a part of the soil . If you remove the mulch after a couple months , however , it will hold much of the excess nitrogen your soil contained , and it can be add to a compost pile or a nitrogen - deficient plot .
6. 15-15-15
The most rough-cut soil tests , unremarkably from state universities , will not give you organic alternatives to balance your soil . Often they will provide the soil pH and nutrient deficiencies , but recommend applying a chemical fertilizer with the desirable NPK ratio . The NPK number present percentages of chemically derived atomic number 7 ( N ) , phosphoric ( phosphorus ) and potassium ( K ) , in that purchase order . However , however you may detect viable natural alternatives . plumage or pearl meal , for example , are both splendid source of nitrogen ; rock inorganic phosphate could be used to sum up Lucifer ; and for atomic number 19 , try wood ash tree or greensand . you could even measure out the equivalent percentage of each ingredient to create a fertilizer of your own to meet the required proportion .

7. Balance with Compost
No matter how you select to rectify your soil , utilizing rich compost before planting is helps guarantee the best harvest potential . In fact , if you could only add one affair to your land , it should be compost . Compost rebalances soil and bring down works disease . It nominate certain nutrient bioavailable to plants . It enriches the grime and adds valuable micronutrients and microorganisms while amend crop quality . Compost might not have a high NPK proportion , but it ’s ability to establish soil structure and counterbalance pH helps plants enter the food that are there and protect those nutrients from leaching .
