FARMING the light lands of the West Midland area would be impossible without fertilisers.
Most light land areas are inherently very low in phosphate and also require nitrogen.
The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.

A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner
A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
An uncrushed skull and associated skeletal elements of a very large rhinoceros are the basis for the description of a new species of Aphelops from Frontier County, Nebraska. The major differences are: the skull is much larger in most dimensions than other Aphelops; it has an extremely elevated occipital region in comparison to Aphelops mutilus; the narial notch is retracted to a point perpendicular to the center of molar one; and the teeth are more hypsodont than any other species of this genus. The sediments which yielded the skull and skeletal parts are considered to be Kimballian in …

Cultivation : Does Haste Mean Waste?, H M. Fisher
Cultivation : Does Haste Mean Waste?, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.
In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan
Seed And Pasture Rates For New Dairy Pastures, F E. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.
Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.
