Mechanisms for nutrient interactions from organic amendments and mineral fertilizer inputs under cropping systems: a review

Abstract

Food security issues continue to be a challenge in most parts of the globe, especially in sub-Saharan Africa (SSA). Several research attempts on addressing this issue have mainly been on nutrient replenishment using combined nutrient application of organic amendments and mineral fertilizer inputs. However, there is limited information available on the potential mechanisms underlying nutrient interactions associated with co-application of organic amendments and mineral fertilizers. Therefore, this review focuses on the mechanisms underlying crop nutrient interactions, with particular emphasis on improved nutrient synchrony, priming effect, general soil fertility improvement and balanced proportion of nutrients required by crops. Following a brief overview of the mechanisms, the review describes four common pre-determined nutrient ratios required by plants depending on its life cycle, environment and genotypic characteristics in order to attain the crop’s maximum genetic potential. The review concludes with the need for future research to understudy mechanisms causing nutrient interaction under cropping systems, so as to apply nutrients at the most appropriate time to synchronize nutrient release with crop uptake, with the utmost goal of promoting sustainable crop production and enhancing food security.

The Impact of Integrated Nutrient Management on Trifolium alexandrinum Varietal Performance in the Indo-Gangetic Plains: A Comparative Yield and Economic Analysis

“…From a nutrient management perspective, the integration of a 75% recommended dose of fertilizers (RDFs) with farmyard manure (FYM) and plant growth-promoting rhizobacteria (PGPR) has demonstrated a synergistic effect on yield [40]. This synergy likely arises from the complementary roles of inorganic and organic fertilizers in improving soil fertility [41]. Inorganic fertilizers provide immediate nutrient availability, while organic matter from FYM enhances soil structure, water-holding capacity, and microbial activity [42].…”

Effects of Different Proportions of Organic Fertilizer Replacing Chemical Fertilizer on Soil Nutrients and Fertilizer Utilization in Gray Desert Soil

“…Organic fertilizer affects these factors more. The biggest advantage of fertilizer is that it can increase the content of organic matter in the soil and improve the fertility of the soil [14]. Owing to the slow effect of organic fertilizer, during the growing season, its application alone cannot meet the needs of farmers to increase crop production [15].…”

Optimizing Nitrogen Nutrient Management for the Sustainable Enhancement of Secondary Metabolites and Yield in Onion Cultivation

“…In the dynamic landscape of modern agriculture, understanding the intricate interplay between fertilization practices, particularly nitrogen (NH 4+ ), iron (Fe 2+ ), and sulfur (SO4 2− ) applications, and their impact on the nutritional profile of crops is imperative [1][2][3]. It is recognized that the selection or recommendation of an optimal fertilization system is crucial for each plant, as it contributes to achieving a high yield and ensuring the quality of plant products for food consumption [4,5].…”
