ingresan al laboratorio. Podrán apreciarse, técnicas, funcionamiento de los instrumentos que se utilizan para lasdeterminaciones y los resultados obtenidos. Con respecto a los objetivos propuestos son: Obtener experiencia en la determinación de análisis quÃ-micos de suelo y agua. Realizar determinaciones quÃ-micas, cuyos resultados orienten sobre la fertilidad quÃ-mica de los suelos y que sea una herramienta básica para Ingeniero/a Agrónomo/a. Ya que permite fijar pautas sobre la producción de los distintoscultivos. ANÃLISIS DE SUELO

Suelo Los suelos se forman por la combinación de cinco factores interactivos: material parental, clima, topografÃ-a, organismos vivos y tiempo. Los suelos constan de cuatro grandes componentes: materia mineral, materia orgánica, agua y aire; la composición volumétrica aproximada es de 45, 5, 25 y 25%, respectivamente. Los constituyentes minerales (inorgánicos)de...
