Structural properties of soil as one of the factors of soil fertility in the works of V.R. Williams

V.R. Williams, one of the founders of the study of soil structure, devoted his long-term research to this property of the soil. His numerous works relate to the conservation and improvement of soil fertility, the influence of mechanical, weather factors on the formation and destruction of soil structure, while his research and recommendations in application to arable land are particularly relevant. Great importance in his work is attached to the use of the grass-growing system of agriculture and the associated introduction of fresh portions of organic matter.
