The introduction of animal traction into inland valley regions. 3. Different cultivation techniques for maize por Dijkman, J.T., Lawrence, P.R.

“…Maize was grown in the upland areas surrounding an inland valley in central Nigeria in a randomized block experiment using six cultivation techniques (manual cultivation with a hand hoe (MC); ploughing in both directions to throw up a ridge (DPL); single ploughing with the seed placed on the ridge (SPL); ridging with a wooden, single tine, locally made ‘bush’ plough (BPL); single ploughing with the seed placed in the furrow (FPL) and ridging with a conventional ridger (RID) with or without pre-emergence herbicide (PEH) with two replicates. …”

Visualizing clogging up of soil pores in tropical degraded soils and their impact on green water productivity por Tebebu, Tigist Y., Baver, C., Stoof, C., Steenhuis, Tammo S.

“…Restrictive soil layers commonly known as hardpans restrict water and airflow in the soil profile and impede plant root growth below the plough depth. Preventing hardpans to form or ameliorate existing hardpans will allow plants root more deeply, increase water infiltration and reduce runoff, all resulting in greater amounts of water available for the crop (i.e. green water). …”

Potato yield and soil physical properties as affected by subsoiling por Holmkvist, Anna

“…Subsoiling is a way to loosen up the plough pan by deeper tillage. General it decreases soil strength and bulk density, the effect is that the roots can penetrate further down in the soil which may reduce stress caused by inadequate water and nutrient supply. …”

Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota por Holmkvist, Anna

“…The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg.
