Soil mean weight diameter
WebDec 28, 2016 · Results showed that both NP- and NPK-treated soils significantly increased mean weight diameter of aggregates, SOC, available P in bulk soil and aggregates, as compared to CK. Most SOC and total N adhered to macro-aggregates (>0.25 mm), which accounted for 64–81% of SOC and 54–82% of total N in bulk soil. WebParticle size is a notion introduced for comparing dimensions of solid particles ( flecks ), liquid particles ( droplets ), or gaseous particles ( bubbles ). The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size ).
