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... 

To help soldiers keep their aircraft, barracks, tents, foxholes, and forest areas clear of malarial mosquitoes, the refrigeration industry and the U.S. Department of Agriculture developed an aerosol gun that sprayed a mixture of DDT, pyrethrum, and Thomas Midgley, Jr. s Freon 12 (Chapter 6). The insect bomb became so popular that it launched the postwar aerosol industry.

The critical role of agriculture cannot be overemphasized as an obvious axiom of the policy of self-reliance, which is the ability to feed its own population. Political slogans such as "Agriculture as Foundation" and "Industry Must Aid and Serve Agriculture" are just some indications of the primary importance accorded to agriculture. (A separate Ministry of Food was established on June 12, 1979, with Zhao Xinchu—full member of the 11th Central Committee of the CCP—as its first Minister.) Agricultural development will continue to be viewed as the fundamental basis for economic modernization, and the point of departure for pursuit of import substitution policies. 

The growing world population requires an ever-increasing dependable supply of essentials for living. Agricultural development of tropical lands has been on the increase for decades. However, only in relatively recent years has intensive agricultural development of these lands become so important.

One species of Euphorbia in Brazil (Bernardia pulchelld) has been determined to contain more than 90% vemolic acid in the triglyceride [120]. This level of single-component purity is equivalent to the level of ricinoleic acid typically found in castor oil. These different varieties of epoxidized oil plants will probably continue to be the subject of agricultural development in the coming years.
