在英国，将产量与土壤结构的定量评估联系起来的出版物相对较少。本文给出了从多年的观测中选出的相关性的例子。在土壤养分或病害的数量不是限制因素的地方，谷物、豌豆和红甜菜的产量与结构的稳定性有关，而结构的稳定性又取决于土壤没有草的年限。在弱结构的土壤中，人们发现，稳定，与空调器，结构开发的种植在低于田间容量的含水量导致显着增加的产量和大小等级的花椰菜。
Summary Relatively little has been published in Great Britain relating yields with quantitative assessments of the structure of soils. This paper gives examples of the kind of correlations found, a selection from many years’ observations. Where the quantity of soil nutrients or disease was not a limiting factor, the yields of cereals, peas, and red beet were related to the stability of the structure which in turn depended on the number of years the soil had been out of grass. On a soil of weak structure it was found that stabilizing, with a conditioner, the structure developed by cultivation at a moisture content below field capacity resulted in a marked increase in both yield and size grade of cauliflowers.
