The following investigation was based on the observation of air temperature conducted at the Agrometeorological Observatory in Felin nearly Lublin in the period 1951-1985. In the successive years and months of this period air temperature deviations from the 35 year average values were calculated. The yearly temperature deviations fluctuated from -1.6º (1956) to 1.4º (1951); monthly deviations were...
В статье приводятся результаты двух экспериментов на 352 и 3699 поросятах по оценке пригодности концентрата, в котором рыбная мука и поэкстракционная соевая мука были замещены обезжиренным молоком в порошке, сушеной сывороткой и дертью зерновых. Эксперимент показал, что использование смеси ПП-престартер и ПП-гровер с участием экспериментального концентрата (1,90 кг) было статистически достоверно ниже...
During the period of 1983-1985 the authors studied the differentiation in the vertical distribution of air temperature over a grass surface and in dense fields of red clover and rye. Measurements were taken at heights of 5, 20, 50, 100, 150, 200, and 250 cm above ground surface. The authors observed a differentiation in the air temperature values with respect to the type of plant cover, the height...
During the period of 1981-1985 measurements of vertical movements of soil were carried out at the Agrometeorological Observatory at Felin, Lublin. During the cool half-year from November through April, the authors analyzed maximum diurnal movements in a decade, decade amplitudes, and the number of days with vertical movements in a decade. Also assessed was the extent of wintering of rye and wheat,...
The authors considered extreme diurnal air temperatures measured at heights of 5. 20, 50, 150, and 200 cm. The mean monthly maximum temperature varied from -1.6° (Jan.) to 24.3° (July), and the minimum - from -8.4° (Jan.) to 11.3° (July). Mean values of amplitude varied from 5.9° (Dec.) to 13.2° (June). With increasing height above ground level a decrease was observed in the (yearly mean) maximum...
