    In the years 1962-1965 at the Agricultural Experimental Station Lipki, the experiment with fertilization and varieties of potatoes was carried out on the light soil of podsol type. In the experiment, the effect of different doses of farmyard manure (200 and 300 q/ha), fertilizers, and peat preparation on three varieties of potatoes: Epoka, Flora, and Lenino was taken into account. The obtained results prove that Epoka reacts best to the fertilization, Flora to the organic manuring, and Lenino to the fertilization with peat preparation.

    In the years: 1950-62 the experiment with fertilization on the terrain of the Agricultural Experimental Station-Lipki in order to determine the productive value of phosphorite meal, high-soluble basic slag and peaty preparation. The researches proved that the phosphorite meal on the soil of podsol type with pH 4.0-4.2 for the most part gives higher productive effects than the high-soluble basic slag. The increase of the meal dose was aimless because the yields of plants increased minimally. The peaty preparation gave highest effects in yields on nitrogen-potassium fertilization and on the background of nitrogen-potassium fertilization with the dose of 36 kg P₂O₅/ha in the form of phosphorite meal.

    The aim of two year farmyard manure experiment with potatoes and spring wheat was to try the forming of productive value of the dungs produced in two terms at the end of winter with two different doses of litter, as well as differently preserved and applied. It was proved that in the first year of experiment the farmyard manure, with the lower dose of litter, spreaded and left in the field, was more effective, and in the second year the farmyard manure with higher dose of litter immediately ploughed under. The addition of water and clay to the manure had no greater effect on its productive value, and the peat preparation was better in the first year than in the second one.

    Wpływ następczy mieszanek z wyką siewną użytkowanych na zieloną paszę na plonowanie rzepaku ozimego.

    In the years 1958-1961, research was carried out on medium-heavy soil to choose the mixture components with spring vetch. After gathering the mixtures, the following effect was tried on the yield of winter rape. The highest yields were obtained after the vetch was sown alone and in mixtures with pulses only. Increased addition of oats (50 kg/ha) and sunflower (15 kg/ha) caused a real decrease in the rape seeds' yield. Lowest yields were obtained after sunflower sown alone.

    Wstępne wyniki doświadczenia nad podniesieniem produktywności gleby bielicowej o wyczerpanym kompleksie sorpcyjnym.

    In the field experiment lime gave the highest productive effects. In the series without the basal fertilization for instance the grain yields of winter wheat as mean yields of four years were 6.0 cwt/ha on full fertilization - about 11.2 cwt/ha, on the other hand on the full fertilization with lime 21.5 cwt/ha, at the same time the farmyard manure effectiveness being applied in dose of 100 cwt per ha yearly was a little lower. Molibdenium applied only once in the dose of 1.5 kg/ha ammonium molibdenlat gave during four years the negative results on all plants. Only the negative effectiveness of molibdenium was neutralized under the influence of farmyard manure.
