The effect of deep and surface manuring on the temperature and water content of sand soils
In connection with growing seedlings of Scots pine, for one year and a half investigations were performed on loose sand soils in order to examine the effect of deep and surface manuring on the heat and water regime of the soil. Following facts could be ascertained: 2. The results pertaining to the l...

Following facts could be ascertained: 2. The results pertaining to the latter problem essentially correspond with From the two procedures tested the effect of deep manuring seems to be more favourable, especially as to the water regime of the soil. 2. The results peratining to the latter problem essentially correspond with those obtained by A. Klime s- S zmik (8), revealing that in the vegetation period the desiccation of the fertilized soil is in its entire profile slower than that of the untreated soil (the manure layer serves as a water depot) and, therefore, the former ensures better water supply for the plants. 3. It should be underlined, that surface fertilizing contributes to quicker and deeper penetration of summer precipitation, but, on the other hand, the soil thus treated dries faster. 4. Surface manuring decreases the extreme changes of temperature of sandy areas: the warming up and cooling down of the soil is equally slower. But, on the other hand, the soil thus treated grows colder, chiefly in rainy periods. 5. The deep manure layer delays the expansion of'heat to the layers beneath it. Moreover, due to its high moisture content, it may also store heat, despite the fact, that its temperature is slightly lower than that of a layer in the same depth in untreated soils. The advantage of deep manuring manifests itself chiefly in decreasing the extremeties of temperature and in ensuring higher temperature in sand soils. However, in case of heavy insolation this effect may become damageous, because the »heat isolation« of the deep manure layer may cause too high temperatures in the layers near the surface. This danger threatens far less if the manure layer is placed into greater. | |
