The article presents the results of long-term research aimed at studying the influence of mineral nutri-tion elements in the technology of growing winter and spring wheat in the conditions of Ulyanovsk region on grain yield and quality, taking into account the soil resources of the region. The winter wheat varieties Bazalt, Saratovskaya 17 and spring wheat – Simbirtsit, registered in Ulyanovsk region, were selected as research ob-jects. Pre-sowing seed treatment and foliar treatment of plants with zinc and manganese sulfate solutions were carried out taking into account the low content of these elements in the soil (Mn ˂ 30 mg/kg; Zn 0.1-0.2 mg/kg; S 0.3-1.3 mg/kg) and their great importance for plant metabolism. This technological method helped to increase the field germination of winter wheat plants of the Bazalt variety with natural soil fertility by 4.5-5.3 % and of spring wheat plants of the Simbirtsit variety with mineral nutrition by 5.2-7.3 %. The yield of winter wheat of the Bazalt variety (3.54-3.75 t/ha) increased by 12.7-22.0 %, that of spring wheat (2.51-2.65 t/ha) – by 13.7-20.3 % on the background without fertilizers. The yield of the winter wheat variety Saratovskaya 17 was 5.46-6.06 t/ha in the variants and the effect of the treatment was less significant. The indicators of pro-tein content in grain and gluten mass fraction did not differ significantly in the variants of the experiment, but the quality of gluten increased in the variants with the joint application of ZnSO4 and MnSO4 on the back-grounds with mineral fertilizers.
Keywords: winter wheat, spring wheat, manganese sulfate, zinc sulfate, yield, protein in grain, gluten.

The current state of the forest belts in the Penza region can be described as unsatisfactory: some areas have been lost, others need to be restored. In this regard, considering the importance for agricultural produc-tion, it is necessary to monitor the condition of the forest belts and assess the impact of their reclamation on the productivity of agricultural crops. The purpose of the work is to evaluate the reclamative effect of field pro-tection forest belts on the productivity of crops in a separate subdivision of the educational and experimental farm "Ramzai" (Mokshansky district of Penza oblast) using GIS technologies. Based on the results of visual interpretation, the scheme of coverage of arable land by reclamative zones was created, their areas and crop yields were determined. When evaluating the coefficients of protective forest cover (PFC) and territory protec-tion (TP), it was found that the value of PFC corresponds to the normative values for the forest-steppe zone, and the value of the TP coefficient indicates insufficient protection of arable land. The results of the calculation of changes in gross yield show that on average over two years, its value of cereals and legumes increased by 4.28%, that of sunflowers by 2.71% and that of forage crops by 5.55%, which is due to the influence of the for-est reclamation. However, in the educational and experimental farm "Ramzai" there are plots where the in-fluence of forest belts is completely or partially absent, which indicates the need to develop and implement projects for the forest land reclamation.
Keywords: geo-information technologies, forest reclamation, forest belts, yield, gross harvest.

The research is aimed at eco-sustainability assessment of landscapes in the Penza region municipalities. To analyze total landscape eco-sustainability, the coefficient of landscape eco-sustainability (CLEC) was used. The current research identified nine municipalities with extremely unsustainable landscape (CLEC = 0.15-0.49), six districts with unsustainable landscape (CLEC = 0.50-0.95) and six municipalities with nearly sustainable landscape (CLEC = 1.12-2.02). In the Penza region, the Gorodishchensky and Kuznetsky districts (municipalities) have sustainable landscape, and the Narovchatsky, Nikolsky and Sosnovoborsky municipalities – extremely sustainable landscape. Obtained results showed general information on the level of landscape eco-sustainability in the Penza region, and would help to choose a better set of measures to stabilize, preserve and restore landscapes.
Keywords: landscape, sustainable landscape, unsustainable landscape, coefficient of landscape eco-sustainability.

The article is devoted to the problem of poultry litter processing for its further utilization and application as a fertilizer. In the last decade, there has been an increase in the specific weight of poultry meat in the scale of livestock production, while the total number of poultry grown on different farms in the Penza region has increased from 9749.5 thousand to 15130.5 thousand. Currently, the annual total output of litter on the poultry farms is about 560 thousand tons, that could lead to environmental pollution in the surrounding area. Litter from local poultry farms contains a high content of nutrients necessary for plants (Ntotal up to 5.7%, P2O5 up to 5.6%, K2O up to 4.4%), that could be used as organic fertilizers or the main component in the production of organomineral fertilizers after composting.
Turkey litter generated at agricultural plots of PenzaMolInvest LLC is characterized by a high content of nutrients and after preliminary fermentation could be used to obtain granulated organic and organomineral fertilizers. Granulation of turkey litter after five months of natural composting at storage sites in pure form and with the addition of mineral components (defecate, phosphate flour or wooden plants’ ash) made it possible to obtain organic and organomineral fertilizers with high properties: nitrogen content of 2.1-4.1%, phosphorus content of 1.6-5.2%, potassium content of 1.7-4.5%, pH of 6.5-8.8, organic carbon content of 29.4-43.3%.
Keywords: poultry litter, chemical content, organomineral fertilizer, agrochemical composition of fertilizers.
