Prediction of mean weight diameter of soil using machine learning approaches
Agronomy Journal, 2021AbstractEven though research shows that aggregate stability and mean weight diameter (MWD) are critical components of soil health, it is not routinely measured. An alternative approach to the physical measurement is to calculate these values based on routinely measured soil parameters. Therefore, the objective was to compare two artificial intelligence

Aggregate analyses of Breton plot soils using a wet sieving technique revealed marked differences resulting from cropping practices but few, if any, due to fertilizers. The mean weight-diameter of soils from plots in a 5-year rotation of grains and legumes was almost double the diameter of soils from plots in a wheat-fallow sequence.

Data collected on three South African Merino flocks were used to estimate genetic and phenotypic correlations of total weight of lamb weaned over three parities (TWW) with two-tooth body weight at 14 to 17 months of age (BW), clean fleece weight (CFW) and mean fibre diameter (MFD).

Abstract The hierarchical organization of aggregates in soil is responsible for the presence of inter and intra-aggregate pores. This research aimed to investigate effects of soil surface liming, considering lime rates of 0, 10 and 15 t ha−1, on the intra-aggregate porous system of soil aggregates with equivalent diameters of 2–4 and 1–2 mm, from 0 ...

Influence of calcium carbonate on mean weight diameter of soil
Soil and Tillage Research, 1988Abstract Lime influences on soil structure and water stability of aggregates are vague and inconsistent. An understanding of the mechanism involved is needed for better management of soil structure. Calcium carbonate was added to soil samples from the BC horizon of two Mollisols to bring the calcium carbonate content to 0, 2, 4, 8, 16 and 32% on a ...

Spatial and temporal variations of mass-weighted mean diameter estimated by GPM/DPR
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Mass-weighted mean diameter D m is explicitly estimated in the GPM/DPR algorithms. The spatial and temporal variations of D m are analyzed by fixing the range of precipitation rates R. Generally, D m is higher over land than over ocean. In India, the seasonal variation in D m is shown. Such spatial and temporal variations are clearly seen for heavy
