Reduced to small particles by beating or striking heavily and repeatedly.
Industry:Agriculture
The potential energy of a unit quantity of water produced by the interaction of the water with such forces as capillary (matric), ion hydration (osmotic), and gravity, expressed relative to an arbitrarily selected reference potential. In practical application, potentials are used to predict the direction and rate of water flow through soils, or between the soil and some other system, such as plants or the outer atmosphere.
Industry:Agriculture
The maximum yield of a cultivar in the absence of any abiotic or biotic stress. e.g., yield obtained in the absence of yield-limiting factors such as water, fertilizer, proper cropping practices and in the absence of yield-reducing factors such as pests and natural calamities.
Industry:Agriculture

Industry:Agriculture
The process of converting exchangeable or water-soluble potassium to moderately soluble potassium.
