Abstract
Wheat (Triticum aestivum L.) is one of the most important cereal crops used for human food. In Egypt, improving wheat production is an essential national target to minimize the wide gap between production and consumption. Use of organic manure might be an effective strategy to improve soil properties and increase wheat yield, especially under sandy soil conditions. The role of organic farming (OF) remains open to debate particularly when related to food security, especially under climate change conditions. Organic farming systems have evolved globally, whereas organic practices can improve soil physical and biological fertility, and soil chemical fertility may be reduced if inputs do not match those removed in produce, leading to mining of soil nutrients. Organic agriculture can reduce many negative environmental and economic impacts that are characteristic of conventional production. Moreover, organic agriculture is a holistic production management system which promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity. Organic systems also show yield stability over variable weather conditions, particularly during drought. In organic farming, the emphasis is on developing healthy, biologically active soil through the use of certified inputs and land management practices. Inputs used in rotations include plant residues, animal manures, rock dusts and biological activators. Additionally, biological activity is promoted so that soil processes such as nutrient cycling and soil structural development are facilitated. The incorporation of organic manure produced significant increase in wheat yield and yield attributes, grain quality, nutrients uptake as well as soil fertility under sandy soil conditions.
