The influence of biohumus fertilization (at a rate of 0, 4, and 8 tha-1) on the microelement (Cu, Fe, Mn, Zn) content in grasses and meadow herbs was compared. Chemical analysis showed that the concentration of the microelements investigated was distinctly higher in meadow herbs than in grasses. The biohumus applied changed the concentration of microelements in both grasses and meadow herbs, but the range of changes depended on the biohumus rate used. Biohumus increased the concentration of Cu and Zn in herbs and weeds by S,07-28,03 and 18,53-75,44 mgkg-1, respectively, and in grasses by 37,50-112,74 mgkg-1. 116 biohumus rate of8 tha-1 decreased the content of manganese in the 1st and 2nd cut.

Results of two field experiments conducted on experimental plots of Agricultural University in Cracow are presented. One experiment was set up on degraded chernozem, the other one on a brown sod developed fiom dump sand The experiment comprissed 8 objects differing in the species of nurse and compation crop plants. At Prusy the test plants were: triticale, spring wheat, faba bean, red clover, and Italian ryegrass, whereas at Wierzbica these Were: triticale, oat, yellow lupine, Serradella, and orchardgrass. The content ofCd, Cu, Ni, Pb, and Zn were determined in seeds, straw, and sod. It was found that the content of heavy nietals in nurse plants depended on soil conditions and the plant species cultivated as a compation crop. The presence of compation crop in ad the plant species investigated increased the content ofCd, Cu, Ni, Pb, and Zn in straw. Legumes decreased the content of Cu and Ni in triticale seeds and Cu, Ni, and Pb in lupine seeds, as well as increased the content ofCu and Pb to wheat and faba bean seeds. The presence of companion crops decreased the amount of heavy metals in the two soils used.
Wpływ biohumusu i nawozów fosforowo - potasowych na plon i zawartość makroelementów w runi łąkowej
(Wydawnictwo Akademii Rolniczej w Szczecinie, 1996) Czyż, Henryk; Trzaskoś, Maria; Akademia Rolnicza ul. Słowackiego 17, 71 - 434 Szczecin, Katedra Łąkarstwa; Akademia Rolnicza ul. Słowackiego 17, 71 - 434 Szczecin, Katedra Łąkarstwa
In the experiment which was carried out on the mineral-peat soil the influence of humus (0,4 and 8 txha(-1) applied after the phosphate-potassium fertilization (P 0K0 and P60K90 kgxha(-1) on the yield and its structure as well as the NPK Ca and Mg content in grasses, and weeds was investigated. The phosphate-potassium fertilization and biohumus had an advantageous influence on the yield of the investigated grassland. Higher effects in protein d were obtained after the application of biohumus without phosphate and potassium and the d of green mass was higher in the objects with phosphate-potassium fertilization. Herbs and Were characterized by a higher content of determined macroelements than grasses. Biohumus had an advantageous influence on the nitrogen concentration and the phosphate-potassium fertilization P and К in both plant groups.
Eksperymentalne retardanty wzrostu w uprawie pszenżyta jarego

Experimental retardants code named IPO 13193, IPO 13194 and IPO 13197 produced by Organic Industry Instytute in Warsaw were tested in the years 1990-1993. The action of retardants in cultivation on of spring triticale depended on the cultivar variety. Tested retardants applied for Jago c.v. in most cases affected blades shortening more favourably than those commonly used in practice. In case of Maja c.v. similar results were obtained with the application of IPO 13193 and control „Antywylegacz płynny” 60 (chloromekwat). IPO 13194 and IPO 13197 retardants produced results similar to those obtained under the influence of Flordimex T (etephon).
Wpływ wieloletniego nawożenia mineralnego i mineralno-organicznego na koncentrację rodników paramagnetycznych i wybrane elementy żyzności gleby

The studies received up to now indicate that only mineral fertilization causes -disadvantageous changes in the soil fertility. For this reason the application of organic-mineral ertilization is recommended because it prevents the negative effects of the only mineral eitilization. The aim of the present work is the study of the influence of the many-years application of different fertilizers combination on the content in the soil of nitrogen and carbon the paramagnetic radicals concentration as well. Or studies performed within the presented work 8 samples were taken from the static field experiment, where the some crop rotation and fertilization were applied during 20 years. It was found that application of the mineral fertilzer causes the increase of C and N content and the ecrease of the paramagnetic radicals concentration in the soil. On the contrary the application W the calcium fertilization leads to high paramagnetic radicals concetration: 1,9 x 1012 rad/g and 6,81x10” rad/g respectively.
