Nutrient Cycling by Cover Crops in Vegetable Growing under Conservation Agriculture | Chapter 07 | Current Research in Agriculture and Horticulture Vol. 1
Nutrient cycling for crop production is
desired to reduce environment impact, enhance nutrients use efficiency and
reduce cost production. Several
agriculture techniques are available to support this possibility for grower and
so give the sustainable production driving for the better nutrient using.
Conservation Agriculture is a current system for crop production that provide
this possibility and it is based in three agronomic principles that are minimum
disturbance of soil or no-tillage for crop establishment, permanent residue on
soil surface and crop rotation. In this context, cover crops is use as crop
rotation in vegetable production and this possibilities the nutrients cycling,
straw production to protect soil surface and improving in soil fertility, among
another benefits to agricultural environment. Because your vigorous root growth
they achieve nutrients that were being lost by leaching in the soil profile e
come back to their shoot recycling nutrients into the system. After, nutrients
will be mineralized and so available to the soil solution and crop nutrition.
Many horticulturists around the world have been using successfully cover crops
as crop rotation to get sustainable in their production and here in this work
we approach some results that support rational using of cover crops for
recycling nutrients in horticultural crops in the context of Conservation
Agriculture. So we certified this efficient function of cover crops to straw
production and nutrient recycling in some crop like tomato, broccolis and
watermelon to get high yield with reduced environmental impacts and improvement
of soil fertility.
