Integrated Phosphorus Management: Symbiosis for Sustainable Crop Production and Improvement in the Income of Smallholders under Semiarid Climates
Soil resources and health is continuously declining due to removal of essential plant nutrients from the soils in the current changing climate scenario. Low and high water and temperature stresses results in the deficiencies of essential plant nutrients especially phosphorus, organic soil carbon and beneficial soil microbes that had negative impact on soil health, crop productivity and grower’s income globally. Integrated management phosphorus along with organic carbon sources and biofertilizers increase soil fertility and health, increase crop productivity and grower’s income. Soil organic carbon management under semiarid climate in soils plays a role in four important ecosystem services: resistance to soil erosion, soil water retention, soil fertility for plants and soil biodiversity. Stable and productive soils having enough organic matter affect the resilience of farms to cope with the effects of climate change. Our long-term field experiments on field crops e.g. cereals crops (rice, wheat & maize), oilseed crops (canola, sunflower & soybean) and grain legumes/pulses (chickpea, mungbean & mashbean) confirmed a significant increase in yield per unit area with integrated phosphorus management under arid and semiarid climates. The combined application of phosphorus along with different biofertilizers (beneficial microbes) + organic carbon sources (farmyard manure; animal manures: poultry manure, cattle manure, sheep manure, goat manure etc.; plant residues: onion residues, garlic residues, wheat residues, rice residues, chickpea residues, fababean residues, canola residues etc.) into the soil had significantly improved crop growth and increased productivity and smallholder’s income.
