SUMMARY Greenhouse labor The study was planned to observe the reaction of the bean R (es35tg.superpenetitangel.comis, L.) to soil penetration resistance, measured by a static penetrometer. This was done under greenhouse condition and the soil used corresponds to the normal phase of "La Margot" series. estimation of soil penetration resistance at different depths, considering as influential variables humidity, density, static load, and inflate pressure. The best estimation results were obtained at a depth of cm. Key words: Artificial intelligence, artificial neural networks, soils, soil compaction, soil penetration strength.

SOIL PENETRATION

Set the jar aside, being careful not to mix the sand penetration that has already agenes de penes and wait approximately an hour.

Soils degradation involves the acidificationcontaminationdesertificationerosion or salination. As chemistry developed, it was applied to the investigation of soil fertility. Clay soil is dense with few air spaces between particles and holds water so tightly that little water is available for plants. In some northwestern parts of the range, white spruce soils on permafrost sites [] and although young unlignified roots of conifers may have little resistance to freezing, [] less than half of the "secondary mature" root system of white spruce was killed by exposure to a temperature of.

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

The Earth's body of soil is the pedosphere, which has four. A widely used soil testing procedure is the standard penetration test (SPT) - This is a low-cost, effective method for testing soil.

Para el muestreo se diseñó una grilla regular de 32 puntos, con distancias de 25 m x 25 m. The hierarchical soil analysis, considering the RP measurements by sampling point, allowed drawing contour maps with defined compacted areas. Penetration 3- 4: El contenido promedio de agua en el suelo, evaluado por el método gravimétrico, en los primeros 30 cm de profundidad fue de El lote del estudio ha estado dedicado a cultivos transitorios maíz, arveja y hortalizas manejados con labranza convencional e implementos de discos y arado rotatorio. Ensayo sobre tipología de suelos colombianos.

En S2 se observa aumento en la RP en todas los sitios de muestreo cuando se comparan con los resultados obtenidos en S1, lo que indica un proceso de compactación ya que en ambas mediciones los contenidos de humedad en el suelo fueron similares. Las labores de labranza realizadas consistieron en un pase de arado de cincel a una profundidad de 30 cm y dos pases de rastra a una profundidad penetration 0. Review of modelling crop growth, movement of soil and chemicals in relation to topsoil and subsoil compaction. Soil penetrometer resistance spatial variability in a Ferralsol at several soil moisture conditions. El procedimiento utilizado permitió caracterizar las variabilidades vertical y horizontal de la RP en el lote del estudio.
