After Flarvest. How do the memory effects shown by the other crops compare with those of winter wheat Winter wheat did not show a memory effect after one year, but oilseed rape does seem to do so. Researchers of the Agricultural Development and Advisory Service found that nitrate production by microbes in the soil after a rape crop increased with the amount of fertilizer given to the crop (R. Sylvester-Bradley, personal communication). One reason may lie in this crop s habit of shedding its leaves as harvest approaches, which means that the microbes in the soil get early access to these residues. This habit might contribute to the apparently smaller efficiency of this crop in using nitrogen fertilizer. The crop may be just as efficient as winter wheat at taking up the fertilizer but drops... 

Regular soil analysis is also important for checking the levels of the important nutrients - phosphorus, potassium, calcium and magnesium. Care should be taken to confirm the method of analysis, because the Scottish system and that carried out by organic laboratories and by Agricultural Development and Advisory Service (ADAS) laboratories have different standards. For instance, on the Scottish system, very low for potassium (the lowest level) is less than 40, whereas the... 

Agricultural development and navigation triggered the construction of several infrastructures in early periods. The Canal Imperial was first projected in 1446, and... 

The International Potato Center, known worldwide by its Spanish acronym CAP, sees the potato and other Andean root and tuber crops as underexploited resources for agricultural development and hunger relief in developing countries. Founded in 1971, CIP has worked to enhance the cultivation, yield, processing, and consumption of potatoes. Its original mandate was expanded to include sweet potatoes and, more recently, other Andean roots and tubers in danger of extinction. 

The University is fundamentally an institution of learning, although research and service by its faculty are certainly of major significance. In addition, the land-grant academic institutions have a mission to help their state realize maximum potential for agricultural development and to contribute to the solution of social, economic, environmental, and cultural problems of concern to the citizens of that state. These missions are carried out through the three closely related functions of resident instruction, research, and extension.

The effects of human activities on the composition of the atmosphere have been clearly detected on local, regional, and global scales. Agricultural development and industrial activities are likely to influence terrestrial ecosystems as well as the climate system. It is therefore important to understand the behavior of the atmosphere, which is so vulnerable to external perturbations and so essential to the climatic and photochemical environment on Earth. 

Another large set of environmental problems is related to waste production and ntilization. All Asian countries are touched by these consequences of urbanization, indnstrialization and agricultural development, and there are many specific regional pecnliarities in how this problem is solved regarding the air, soil, fresh and marine waterpollntion, hnman and ecosystem health.
