2005–2010 között a Szent István Egyetem Növénytermesztési és Biomasszahasznosítási Bemutató Központjában Gödöllőn másodvetésű zöldtrágyázási kísérletekben vizsgáltuk különböző zöldtrágyanövények (facélia, mustár és olajretek) hatását a talajellenállásra, a talajnedvességre, illetve a gyökérfejlődését. A 2009. száraz, és a 2010. nedves évek kivételével az átlagos évjáratokban minden zöldtrágyanövénynél szignifikánsan nagyobb talajellenállást mértünk, mint a kontrollnál. A zöldtrágyanövények gyökérzete a rövid vegetációs idő miatt csak a talaj felső rétegét hálózta be, ugyanakkor a különbség a gyökerezési mélység alatt, még a 40–50 cm-es talajrétegben is kimutatható volt. A talajnedvesség-mérés egyik évben sem mutatott statisztikai különbséget a kezelések között. Az őszi bedolgozás után tavasszal ismételten elvégzett mérések során sem a talajellenállás, sem a talajnedvesség esetében nem lehetett szignifikáns különbséget kimutatni a kezelések között. A növényborítottság miatt fellépő nagyobb talajellenállás oka, hogy a gyökérzet oldalirányú növekedésével nyomást gyakorolt a talajra. A növények bedolgozását követően a zöld növényi gyökerek gyorsan elbomlottak, a helyükön kialakuló szerkezetes talaj ellenállása pedig tavaszra megegyezett a kontrolléval. A kutatás több paraméterre kiterjedő eredményei alapján mindhárom növényfajt alkalmasnak találtuk zöldtrágyázásra, de talajba dolgozásukat csak későősszel javasoljuk, és lehetőség szerint csak tavaszi vetésű kultúra kövesse azokat.

There were analyzed and disclosed the basic components of arable farming systems and their Meaning, the current state and scientific principles in the context of the further development of field crop cultivation in the conditions of Western Forest-Steppe. The purpose of research. To study an effect of alternation of crop in crop rotation in conditions of brief rotation on the soil water regime, productivity and economic efficiency. Methods. Field, laboratory, comparative and analytical. Results. The results of researches on study of productivity of four-field crop rotations with short rotation depending on their saturation by the grain and tilled cultures, of various use of mineral fertilizers, green manure crops and collateral products which were conducted during 2014-2015 in the stationary experiment of the scientific and technological department of plant growing and arable farming, of the TDSGDS of the IKSGP of NAAN are resulted In the article. The elements of the biologization of farming are the basis of our development of crop rotations with short rotation. The study of the effect of green manure crops and collateral products in four-field crop rotations with a different set of crops on the change of soil fertility and productivity of crop rotations as a whole was carried out to this purpose. According to the results of the research, is provided the information on the effectiveness of improving the field crop rotations with short rotation with varying degrees of saturation by grain and tilled crops, that ensure the production of environmentally friendly products, reducing the cost of grain, improving the quality of marketable products. The study of the effect of alternation of crop in crop rotation in conditions of brief rotation on the soil water regime, productivity and economic efficiency showed that an increase in crop rotation productivity is observed in short-rotation crop rotations, if they are saturated by grain crops up to 100%, cereals crops reduction to 50% in crop rotations contributes to a decrease in crop productivity. Conclusion. Thus, the results of the research showed that with the correct construction of short rotational crop rotations, such problems as rational use of nutrients and soil moisture, control of weeds and pests of agricultural crops, improvement of the physical and chemical properties of the soil, increased efficiency in the use of fertilizers and equipment, Cheapening of the received agricultural product may be solved.

Nowadays, there is a growing interest in pro-environmental foods produced by pro-environmental practices. However, consumers’ payment motivations towards such foods are currently poorly understood. This manuscript provided a critical investigation of Chinese consumers’ intention to pay a premium (ITPP) for rice grown with green manure as crop fertilizer (GMR). One focus was the establishment of an explanatory structural research framework that includes effects of environmental behavior spillover (EBS) and public information induction (PII); another focus was to analyze the impacts of the selected structural elements on ITPP by introducing education as a moderator. Results suggest that consumers’ ITPP can be largely influenced by PII, therefore, for GMR marketers and policy makers, measures should be developed to widen consumers’ access to public information related to GMR and to improve their capacity of screening effective information. EBS, when ITPP remains low, emerged as a pivotal predictor of consumers’ ITPP. This observation provides us with the enlightenment that breeding consumers’ daily environmental behaviors is highly valued to inspire their payment intention in the early stages of GMR market development. Another finding is that, with the introduction of the educational variable, the influence coefficients of EBS and PII on ITPP increased from 0.42 and 0.53 to 0.61 and 0.66, respectively, which means that it is possible to boost consumers’ payment intention by improving their educational attainment. This study contributes to the existing literature by providing empirical evidence for the GMR industrial upgrading strategy and have significant implications for the environmental governance of the agricultural sector.

AbstractThis study characterized the effect of green manures (February orchid, hairy vetch, rattail fescue and a no-green-manure control) and the termination method (flail or disk) on nutrient contents, enzyme activities, microbial biomass, microbial community structure of rhizosphere soil and vegetative growth of walnut tree. All three selected green manures significantly enhanced the water content, organic C, total N and available P. The rattail fescue significantly decreased the mineral N. Total organic C, total N, mineral N and available P were significantly greater under flail than under disk. Hairy vetch and February orchid significantly improved levels of soil β-glucosidase, N-acetyl-glucosaminidase and acid phosphatase activity, whereas rattail fescue improved only β-glucosidase activity. All of the green manures significantly decreased phenoloxidase activity. β-glucosidase, N-acetyl-glucosaminidase and acid phosphatase activities were significantly greater under flail relative to disk. The termination method had no significant effect on phenoloxidase activity. The different types of green manures and termination methods significantly altered the soil microbial biomass and microbial community structure. The green-manure treatments were characterized by a significantly greater abundance of Gram-positive (Gram +) bacteria, total bacteria and saprophytic fungi compared to the control. Hairy vetch significantly decreased the abundance of arbuscular mycorrhizal fungi (AMF) while February orchid and rattail fescue increased their abundance compared to the no-green-manure treatment. The abundance rates of Gram+ bacteria, actinomycetes, saprophytic fungi and AMF were significantly greater in soils under flail than under disk. In terms of vegetative growth of walnut tree, hairy vetch showed the greatest positive effects. The growth of walnut tree was significantly greater under flail relative to disk. Our results indicate that green-manure application benefits the rhizosphere soil micro-ecology, rhizosphere soil nutrient contents and tree growth. Overall, the hairy vetch and flail combined treatment is recommended for walnut orchards in northern China.
