In large scale, soil texture is the primary gist for soil classification and rational crop layout. However, for crop yield-scaled land the effect of organic farming on biodiversity is highly debated due to the significantly lower yields compared to conventional farms. Here are few ways in which you can improve soil fertility and enhance production: Organic matter. Importantly, using compost made from recycled resources is sustainable and can increase soil organic matter and water holding capacity. Soil organic matter is important in relation to soil fertility, sustainable agricultural systems, and crop productivity, and there is concern about the level of organic matter in many soils, particularly with respect to global warming. Plant take nutrients from soil from 2 sources namely – organic matter and minerals. Years of not replenishing the soil with organic matter forces farmers to add synthetic fertilizers.

Organic matter is important for crops because (a) it helps in improving soil structure. [1] In ancient farming practices, farmers did not possess the technology or manpower to have a significant impact on the destruction of biodiversity even as mass-production agriculture was rising. If the dirt is healthy then there should be no need for fertilizers. In terms of soil texture, those made up of smaller particle sizes, such as in the case of silt and clay, have larger surface area. Nutrient exchanges between organic matter, water and soil are essential to soil fertility and need to be maintained for sustainable production purposes. It’s akin to humans eating a balanced diet. In addition to providing nutrients and habitat to organisms living in the soil, organic matter also binds soil particles into aggregates and improves the water holding capacity of soil.Most soils contain 2-10 percent organic matter. Diversified cropping and mixed crop-livestock systems enhance biological control of pests and diseases through species interactions. Because the maximum possible yields achieved in farmers' fields might level off or even decline in many regions over the next few decades, reducing the gap between average and potential yields is critical. Therefore, to understand nutrient availability and optimal growing conditions for specific crops, it is important to understand factors that affect soil pH, and the effects of pH on nutrient availability. These crops have the potential to increase soil organic matter and fertility, reduce erosion, improve soil structure, promote water infiltration, and limit pest and disease outbreaks. Organic matter is important for crops because. Critical to crop production, soil moisture holding capacity is even more important here than in southern South Australia where irrigation is available. 2.CEC also determines the pH of the soil,hence appropriate technique to buffer it is realised hence ensuring maximum crop production. 115, pp. Soil texture and organic matter are the key components that determine soil water holding capacity. They also supply a steady release of nutrients to plants, inhibit erosion, and host a robust population of beneficial microorganisms. However, even in small amounts, organic matter is very important.
