Ask nature about the secret of opimum ferility
What is optimum soil fertility to grow perfect crops? Many farmers wrestle
over this issue endlessly. ey are always thinking about how to use rice bran,
perilla seeds pulp (what is left of perilla seeds after oil is extracted) and press cake
as organic fertilizers (these are the most common choices in Korea). Growers also
speculate whether they should add blood powder or shell powder or bone pow-
der. en, just how much should they add? ey have asked these questions for
the last few decades but still have not found the answer. Growers have the habit

of confusing themselves and others. We’d rather ask: why are things getting all
the more confusing? is is because you do not have a philosophy, a criterion, a
perspective to make sound judgments. Here is my advice: always look at the
issue of fertilizer from the
nutritional balance
perspective.
So you heard that organic farming is good. You stacked up your warehouse
with environment-friendly products and did your best every year. But still,
something does not seem right. Every year your crops suffer from early lower-
ing, chilling and freezing. When spring rain arrives, they produce copious water
sprouts. Despite your best efforts, problems continue to plague your ields. Is it
the same for nature? Is it so difficult for nature too? Does nature suffer from the
same problems as you? When I look at the mountains I see no early lowering,
no chill damage, and no frost damage whatsoever. What is more surprising, de-
spite the plentiful amount of organic matter in the soil, when spring rain comes,
there are no water sprouts after normal, new sprouting has inished. e answer
to optimum soil fertility is, again, in nature.
Nature does not use rice bran, perilla pulp or press cakes in achieving opti-
mum fertility. en how is it done? Let’s look at how the soil that is in contact
with tree roots is formed. Leaves fall in autumn. ey are the product of photo-
synthesis of nutrients, water, sunlight and air. Grass and other wild vegetation
wither and fall too. is colorful scene that we see every year is how nature ac-
quires the organic fertilizer it needs. en what about the inorganic nutrients
that crops need for growth? If you dig below a tree, you will pass a layer of dark
brown, leaf mold soil and reach grains of coarse sand and rock sediments. ey
will be moist and have a strong “microbe-ish” smell – the microorganisms are
working on the rock, breaking it down into mineral nutrients, which are food
for the plants. Once again it is surprising how simple yet effective the solution is.
is is the secret of nature that frees you from the problems of early lowering,
chill and frost damages, and water sprouts caused by excessive nitrogen uptake.
Apply this part of nature’s cycle to your soil. All of your
crop residues
