The need for decreasing the reliance on chemical products in crops fertilization and the ever-growing land degradation, as a result of intensive use and unsuitable crop management, puts an obligation on growers to search for more reliable and sustainable alternatives, Lal (2007).
Glacial till soils are generally difficult to cultivate and thus unsuitable for cropping, so the most important cultivated land areas in this region are alluvial soils along river valleys and the shores of major lakes.
Camels, unlike other livestock species, are uniquely adapted to hot and arid environments that are unsuitable for crop production, thus contributing significantly to the food security of pastoral households (Ahmad et al. 2010).
It has been estimated that one-third of the world's irrigated land is unsuitable for crops due to its saline condition (Frommer et al. [1999]; Wasti et al. [2012]).
Because of poor-quality soil, much of Wales is unsuitable for crop-growing and livestock farming has traditionally been the focus of agriculture.
In intensively farmed areas where agricultural practices appear to have made cropped land unsuitable, gardens are an important breeding habitat.
Protect weak crops with strip cropping.
The latter species has almost entirely replaced the formerly used black mustard (Brassica nigra), which was unsuitable for mechanized cropping and which now occurs mainly as an introduced weed.
We reasoned that a strict segregation of food and energy crops with a restriction of energy crop cultivation on economically marginal land and land unsuitable for food crop production is unlikely to mitigate the current situation of biodiversity loss originating from intensive agricultural systems on productive land, especially in the European context.
A perennial crop often considered a pest, nettles grow on land often unsuitable for other crops without the need for pesticides, herbicides or much water.
