Higher productivity in Danish arable crop production [PDF]

The projected expansion of organic farming in Denmark is conditioned on increased arable crop production, which requires higher and more stable crop yields. This must be achieved while also phasing out the use of imported conventional manure and reducing

Soil fertility [PDF]

, 2015
Africa?s consumption of fertilizers is the lowest in the world and organic matter that could, to some extent, replace fertility, is often burnt and soils left bare to the degrading effects of the sun and the wind.

Field scale tests of the modified moldboard plow [PDF]

, 1991
In 1989-90 four trials were conducted in southwestern Ontario to study the effect of moldboard modifications on the field scale residue management potential of the moldboard plough.

Determining efficiencies of various moldboard ploughs in fragmenting and tilling air-dry soils

Soil and Tillage Research, 1987
Abstract Heavy tillage implements, such as ploughs, used in semi-arid and arid regions are developed and produced for the temperate, humid regions of the world. Therefore, they are not operationally optimized for the air-dry soils on which they operate in arid or semi-arid regions, and their energy efficiency is not known.

Geometric characterization of moldboard plough using coupled close photography and surface fitting model

Soil and Tillage Research, 2017
Abstract Designing a moldboard plow is a complex task. In many cases, moldboard plows are manufactured mostly based on experience and empirical methods The objective of this study is to identify a way to use a mathematical approach for the design. Therefore, both the mathematical surface (multi variable equations, NURBS and Bezier) and the number of ...
