There has been studied the activity of ferments of urease, catalase (high meanings) and phosphatase (low meanings) and cellulose' decomposition (medium meanings) in soil of tea plantation under the influence of mineral fertilizers. There has been established the seasonal dynamic of biological activity' indicators of acid brown forest soil. The studied changes were caused by weather conditions ...

There are given the findings concerning heavy metal content in leached chernozem while a prolonged application of fertilizers in the article. It has been established that mineral fertilizers can not be treated as a source of pollution of soil with heavy metals. The accumulation of heavy metals in soil exceeding the MPC will be reached only in several thousand years even when triple doses of fe ...

In 2001-2009 the effect of oxyethylidenbiphosphone acid (OEDP) and сomplexones (CP: Zn-OEDP, Cu-OEDP, Mo-OEDP, Co-OEDP) on vegetable crops in a rotation was studied (the Moscow Region). Soil of the tested site was sod-podzolic loamy of 2.2% humus, a total nitrogen content was 0.14 mg/100 gram, pH 5.4. CP were applied by plowing for cabbage crop (CB), the after-effect was studied in regards to ...

Efficiency of growth regulators in combination with microfertilizers for table root crops

Petrichenko, V.N., All-Russia Research and Development Inst. of Vegetable Growing et al. [2011]

In 2007-2009 the effect of Si-containing growth regulator Energia-M (EM) on yield of carrot and beet was studied (the Moscow Region). Soil of the tested plot was sod-podzolic loamy, of 2.2% humus, a total nitrogen was 0.14 mg/100 g. EM was used in various combinations with microfertilizers (Rastvorin B (RB) and Akvarin 5 (A5)) for treatment of seeds (1 g/kg, working solution of 1 l/kg). The be ...

Influence of microfertlizers and growth regulators top-dressing on chemical compound of table root crops

Loginov, S.V., State Research Inst. for Chemistry and Technology of Organoelement Compounds et al. [2011]

A possibility of using Si-containig growth stimulants was shown for vegetable growing. It was established that the preparation Energia-M (EM) in a combination with microfertilizers (Rastvorin B (RB) and Akvarin 5 (A5)) significantly influenced on chemical composition of carrot and beet storage roots. EM was used in various combinations with microfertilizers (Rastvorin B (RB) and Akvarin 5 (A5) ...

In 1987-2005 experiments were done in the apple orchard. Influence of mulching (MC), liming (LM) and of a sod-humus system on pratal chernozem soil fertility was studied. MC by wood sawdust and black paper increased Ca content in soil. LM increased Ca activity and Ca content up to the level of virgin soil fertility, and optimized exchange and hydrolytic acidity (HA). Ca content was 18.3 millie ...

There was studied the influence of different forms of organic fertilizers on the soil biological activity (SBA) and on the yield of spring barley. The experiments were performed in the Nizhnyi Novgorod region in 2009 on light grey forest mean loamy soil containing 2% of humus. The experimental design: 1 is control (no fertilizer), 2 straw (cutting), 4 t/ha, 2 fresh no litter chicken manure, 10 ...
