Plants also provide animals with shelter, produce clothing material, medicines, paper products, reduce noise levels and wind speed, reduce water runoff and soil erosion. Loam is the best type of soil which helps grow the best possible crops because it provides the necessary elements. It is thus possible to change the food value of the plants in either the fresh or the cured condition through methods of treatment and handling of the soil and plants. The nutritive value, succulence, and crude fiber of crops may thus vary greatly, depending on the amount and kind of fertilizer applied or the amount and time of water irrigation. The agronomist accomplishes the same end by cutting, mowing, pasturage, and other practices. In addition the nutritive value of animal products as regards mineral content and, in a large part, vitamins is dependent on the plant foods they consume. The Lee Foundation for Nutritional Research. My thought can be very simply stated. Soils also protect plants from the destructive biological, physical, and chemical activities and equally shield them against erosion. Many factors affect the growth of plants and their value as food. The effects of degree of maturity, age, and type of plant, its rate of growth, harvesting and storage conditions, and manufacturing processes on the quantity and availability of the nutritionally essential elements should be investigated. A vital function of soil is storing and supplying minerals and nutrients essential for plant life. Investigations should be made, therefore, of the nature or availability of the compounds occurring in soils and how they are affected by chemical and biological processes in the soil; of the periodicity of their intake or distribution within the plant; of the differences among species of plants or among strains within a species in their need for mineral elements and their ability to accumulate them; and of the effects of chemical additions to the soil on the composition of the plant. By Dr. E.C. While the effects of the various minerals, soil conditions, management practices, and environmental factors on plant growth and development are being determined, plants produced in controlled experiments and various soil areas should be fed to the usual laboratory test animals in order to determine how their rate of development, general health, and behavior are affected. It takes thousands of years for rocks to weather into soils, and hundreds of years for rich organic matter to build up. This emphasizes the importance of knowing whether the necessary and desirable nutrients are available in the different soil types of the various regions in the countryâto insure not only crop productivity but also that such crops may contain these elements. Much information on these points is already available, but one of the great needs now appears to be that of making accurate studies and complete analyses of agricultural soil types and areas, and the crops that grow on them, under known conditions of climate, fertilization, variety, irrigation, and stage of maturity to determine whether deficiencies or excesses of certain elements occur in such soils and plants and, if so, to correct the conditions, with the ultimate view of improving the health of human beings. Growth of Plant and pH of Soil. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today? Thus, by practices such as spraying, pruning, and shading, the horticulturist can influence the capacity of plants to synthesize, translocate, and store carbohydrates. The minerals and other substances absorbed by the plant from the soil, water, or atmosphere are combined with the carbohydrates or other materials formed from them and help make up such compounds as proteins, fats, vitamins, and other growth and regulatory factors. They are also most essential part of the life of all the organisms living on the earth. Some Soil Deficiencies Resulting in Nutritional Disorders of Plants and Animals. Obviously here is a case where an interrelationship must be studiedâthe interrelationship between the physical well-being of man and the factors in the soil that affect the composition and development of plants. Some time ago in Australia, and more recently in New Zealand, the lack of cobalt in certain soilsâand thus in the plantsâwas determined to be the cause of the so-called âbush sicknessâ of sheep; the addition of cobalt is now preventing the trouble. The role of plants and animals in soil formation is very significant. One of the most important roles of soil organisms is breaking up the complex substances in decaying plants and animals so that they can be used again by living plants. Soil is regarded as life and the pillar of agriculture because it is the medium onto which most plants grow. 3. That method was necessitated by the vastness and complexity of the facts with which science deals, and it is still necessary. Guest Blog Post Submission Form. Protein content decreases and crude fiber increases with maturity. It would be no revolutionary step for us to think in terms of nutritional quality as well. Any foods shipped from such areas would be equally valuable to consumers everywhere. Soils hold water (moisture) and maintain adequate aeration. Research on the individual phases should be coordinated, with each contribution pointed to the same final objective. The investigations should include thorough studies of proteins, amino acids, carbohydrates, fats, vitamins, enzymes, hormones, other growth accessory substances, the ordinary minerals, and the so-called âtraceâ or ârareâ elements and their effects on man. Reprinted from Science, Vol. Soils protect plants from erosion and any other destructive physical, biological and chemical activity. This field is for validation purposes and should be left unchanged. But even making such allowances, the differences in percentages of some elements are so large as to leave little doubt that they are due to the presence or absence of certain elements in the soil. Many of the elements just mentioned are likewise important for the best development of man and animals. The interrelation of the various cultural and management practices as affecting the composition and growth of plants has been well described by Kraus and Kraybill5 and need not be discussed here. It is an anchor for roots and also holds water needed by plants for moisture. Insects and microbes (very tiny single-cell organisms) live in the soils and depend on soils for food and air. Consideration should also be given to the digestibility and utilization in the [human] body of the various plant compounds in relation to other factors affecting metabolism and growth. Therefore, the useful molecules in the soil move down a concentration gradient and into the roots to be taken up by the plant. Even today there are regions where troubles such as goiter, skin diseases, weak and deformed leg bones, mottled and furrowed teeth, and nervous disorders are all too common. We have demonstrated that we have the personnel, the training, the facilities, and the equipment to make some very significant contributions. Animals take in their nitrogen by eating the plants. Protozoa prefer to live in the watery regions of the soil. Source: www.aces.uiuc.edu.com [products tag="patrick-earvolino" limit="3"], +1 (866) 407-9323 In the past serious bone, skin, digestive, and nervous disorders, among other maladies, occurred in certain localities. 2.The oxygen that animals breathe comes from plants.
