The soil was a deep silty-clay loam, with an organic matter content of 1.6% (0–30 cm). The cultivar Soissons was grown in 16 plots (8 preceding crops × 2 input levels). Preceding crops were faba bean, maize, pea, rapeseed, sorghum, soybean, sunflower, and wheat.

24 maj 2024 · Soil texture refers to the relative proportion of sand, silt and clay size particles in a sample of soil. Clay size particles are the smallest being less than .002 mm in size. Silt is a medium size particle falling between .002 and .05 mm in size.
Fenn et al. (1992) have devoted a study to urease activity in two arid, silty clay loam soils (from Harkey and Saneli), each represented by a cultivated, cotton (Gossypium hirsutum) field and an adjacent roadbed site (40 years without cultivation).
The soil is a heterogeneous medium consisting of solid, liquid, and gaseous phases in various proportions. Plant nutrients diffuse essentially in the liquid phase only, at least in the life span of a root segment. Furthermore, part of the soil nutrients are bound to the soil matrix and as such are immobile.
21 gru 2023 · Soil properties at 0–30 cm depth analysed were dry bulk density, soil organic matter content, saturated volumetric water content and saturated hydraulic conductivity. After the tillage and seeding operations, soil organic matter increased on all conservation tillage plots (RT, OT and NT) but decreased under CT.
This study exploited temporal and spatial changes in bulk density and their influences on the changes in some hydraulic func-tions of a Haplic Luvisol under three tillage options: (1) reduced tillage (RT), (2) strategic tillage (ST), and (3) conventional tillage (CT).
