Highlights ► Conservation tillage promoted good corn yields without contaminating groundwater of fragipan soils. ► Pre-emergence herbicides and post-emergence Roundup resistant corn control weeds. ► Conservation tillage on sloping lands with shallow fragipan will sustain long term...
Highlights ► Earthworm community in ploughed fields was dominated by A . caliginosa and A . rosea . ► A . caliginosa was more sensitive to the ploughing than A . rosea . ► Some months after ploughing, abundance did not differ anymore between the ploughed and the unploughed treatments.
Highlights ► Long term N and P fertilization enhanced C input but did not affect soil C content. ► Tillage practices affected C accumulation, and P and pH stratification. ► N fertilization reduced pH, and this trend was reverted by the application of lime. ► S and micronutrients did not...
Highlights ► Soil labile organic C fractions were sensitive to changes in management practices only in the upper soil profile. ► Compared to the single or double CT without crop residue treatment, the double NT with or without crop residue treatment had greater carbon management index at...
Highlights ► A new method for scaling Richards’ equation (RE) have been developed in this manuscript. ► This method goes beyond previously developed methods to applications for dissimilar soils. ► Using this method, a Philip-type model has been developed for constant-head infiltration....
Highlights ► Tillage and crop rotation were more important variables than N fertilizer rate in affecting stratification ratio of soil properties. ► Conservational tillage increased stratification ratio of total N, WSC, AC and enzymatic activities, but did not generally affect SOC. ► High...
Highlights ► We examine evaluated the effect of soil use on the stability, morphology and roughness of aggregates, bulk density and penetration resistance. ► Mollic epipedons of Typical Argiudolls of Buenos Aires with different soil use were analyzed: cultivated, pasture, and natural plots....
Highlights ► Mercury porosimetry detects small pores that are not revealed by micro-CT. ► Micro-CT is fundamental for morphological studies. ► Micro-CT is not influenced by the “ink bottle” effect. ► Soil fertilisations affect pore morphology and pore network organisation.
Highlights ► Methods used in a large-scale study produced reliable soil physical property results. ► Soil physical properties differed between tilled and untilled agricultural systems. ► Temporal changes in soil properties differed between tilled and untilled systems.
