It is very difficult to determine certainly the precise factor which is responsible for the poor growth of a specific plant under e given acid soil from the fact that numerous soil parameters change as the acidity is altered. In the present paper, predominant factors for poor growth of three kinds of crop plants on acid soils different in acidity was determined by the method that to control plot a complete rate of mineral elements was omitted. The results obtained were as follows: 1. Good growth of radish plants in comparison to the other two plants was considered to be due to a lower sensitivity to aluminum toxicity and higher ability to accumulate mineral elements from kuroboku and its subsurface soils. 2. The poorer growth to tomato plants than egg plants was mainly based upon higher sensitivity to aluminum toxicity. 3. The predominant factors for poor growth were potassium, magnesium and calcium deficiencies in radish plants, potassium, phosphorus and nitrogen deficiencies in egg plants and aluminum toxicity, calcium and molybdenum deficiencies in tomato plants in kuroboku soil. 4. The predominant factors for poor growth of these plants were respectively nitrogen and phosphorus deficiencies in kuroboku subsurface soil. |

Wireless sensor networks are gaining importance in agricultural applications, such as monitoring crops microclimates. Precision agriculture is one of the areas that can most benefit from this technology in the sense that wireless sensors networks allow data collection with high resolution, enabling better decision making. Such networks have restrictions on their deployment in a real environment, for example, on energy. Thus, several studies have been conducted in order to optimize the use of this technology. Depending on the application, it is desirable that the available energy on sensor nodes batteries allows operation for months or even years. One proposed solution to extend the lifetime of sensor nodes, so as to avoid unnecessary data collection, is the implementation of a routing protocol that allows a differentiated data sampling. An application that can benefit from this approach is vineyard microclimates monitoring, which is very important to monitor temperature and reIative humidity, and can apply precision agriculture techniques to the crop. Thus, in the program to be installed into sensor nodes, rules for data collection are defined, so that the value collected by the sensor at a given time is in the rule that defines normal conditions, the rate of sampling data used will be higher; however, when the value collected by the sensor is out ofthis rule, the sampling rate will automatically be reprogrammed to a higher value. This differentiated data collection allows savings in power consumption under normal conditions, and generates less data to be analyzed.
