Efficiency of the Inorganic Fertilization in the Cultivation of Alfalfa (Medicated Sativa L) and Whitewashing for the Correction of the pH of the Soil

Bravo Morocho, Alex Gonzalo 01 January 2001 (has links) (PDF)
In our country the necessity to offer new alternatives for the agricultural sector is high-priority especially for the lucern cultivation that every day is surface cultivated especially in the Chimborazo province increases; for what is of our interest to establish the answer from the cultivation to the inorganic fertilization and liming for the flora pH correction, for this way to obtain better yields and for consequence to improve the economic conditions of the farmers. With the result that the titled investigation: Efficiency of the Inorganic Fertilization in the Alfalfa Cultivation (Medicago sativa L) and Liming for the Correction of the pH of the Flora had the following objectives: to determine inorganic fertilization efficiency in the lucern cultivation and liming for the correction of the pH of the floor; to evaluate the production of the lucern cultivation; to carry out an economic analysis.
