Abstract EN
Transformation of organic residues into plant-available nutrients occurs through decomposition and mineralization and is mediated by saprophytic microorganisms and fauna.
Of particular interest is the recycling of the essential plant elements—N, P, and S—contained in organic residues.
If organic residues can supply sufficient nutrients during crop growth, a reduction in fertilizer use is possible.
The challenge is synchronizing nutrient release from organic residues with crop nutrient demands throughout the growing season.
This paper presents a conceptual model describing the pattern of nutrient release from organic residues in relation to crop nutrient uptake.
Next, it explores experimental approaches to measure the physical, chemical, and biological barriers to decomposition and nutrient mineralization.
Methods are proposed to determine the rates of decomposition and nutrient release from organic residues.
Practically, this information can be used by agricultural producers to determine if plant-available nutrient supply is sufficient to meet crop demands at key growth stages or whether additional fertilizer is needed.
Finally, agronomic practices that control the rate of soil biota-mediated decomposition and mineralization, as well as those that facilitate uptake of plant-available nutrients, are identified.
Increasing reliance on soil biological activity could benefit crop nutrition and health in sustainable agroecosystems.
