| Nitrogen (N) deficiency is a major problem in organic and low-input farming systems. Growing spring cereals with undersown legumes has a positive effect on soil fertility, enriching it with nitrogen, through symbiosis of legumes with nodule bacteria. Two hypotheses were tested: 1) undersowing of red clover increases the protein content of barley grains and 2) mineral N has negative aftereffect on growth of legume plants. The aim of this study was to investigate the effect of organic (cattle manure, off-season cover crop) and mineral N in organic and conventional farming systems on (i) barley (Hordeum vulgare L.) grain yield and quality, (ii) biomass yield formation of undersown red clover (Trifolium pratense L.) and (iii) the aftereffect of mineral... |

| Nowadays, organically produced products have become more popular than ever and interest in them is still growing fast. The early blight causal pathogen Alternaria solani has not been considered a great threat to potato in northern climate conditions in the past and has not been routinely sprayed against. During our study early blight was evaluated in 2010 and 2011 on the plants of a potato cultivar ‘Reet’ in an organic farming experiment. In our study, both growing seasons were very favourable for early blight development. Significant differences between the two cultivation technologies were found (F1,12 = 4.84, p = 0.048). In 2010, the area under disease progress curve (AUDPC) value was 303 on cover crop (CC) plots and 990 on CC + M (manure)... |

| The interest of organic farmers for adopting conservation agriculture practices is currently growing. But, there are few technical and scientific references available for organic farmers when they start applying conservation agriculture practices. The main objectives of this study are (1) to explore the diversity of crop management practices using conservation agriculture methods among European farmers, and (2) to identify main farmers’ strategies. We carried out a survey of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a multi factor analysis followed by clustering to identify groups of farmers that share the same type of spring and winter crop managements. Organic farmers in Europe,... |

| The effects of different winter cover crops and their combination with composted cattle manure on weeds and crop yields were investigated within a five-field crop rotation (barley undersown with red clover, red clover, winter wheat, pea, potato) in three organic cropping systems. The control system (Org 0) followed the rotation. In organic systems Org I and Org II the winter cover crops were used as follows: ryegrass (Lolium perenne L. in 2011/2012) and a mixture of winter oilseed-rape (Brassica napus ssp. oleifera var. biennis) and winter rye (Secale cereale L.) in 2012/2013 before pea; winter oilseed rape before potato and winter rye before barley. In Org II system composted cattle manure was also applied. In comparison with the control system, the... |

| A five-year experiment results, have shown that fertilizer amendments are needed for preserving the nutrient balance in the soil. A combination of cattle and green manure, crop rotation and other organic farming practices, with chemical fertilizer amendments could suppose a sustainable solution for maintaining a correct nutrient balance in the soil in long term, better than both farming systems, conventional and organic, by separate. |

| Taimedele oluliste makrotoiteelementide (N, P, K) sisaldused mullas on 10 aasta jooksul nii mahe- kui ka tavasüsteemi kõigi variantide mullas vähenenud. Lämmastikukadu mullast oli mahesüsteemi variantidel väiksem kui tavasüsteemi variantidel, seega mulla lämmastikusisalduse järgi oli maheviljeluse süsteem mullaviljakust säästvam kui tavaviljeluse süsteem. Mulla fosforisisalduse taset hoidev oli mahesüsteemis väetamisvariant, kus kasvatati talviseid vahekultuure ja külvikorra jooksul väetati taimi kolm korda sõnnikuga ning tavasüsteemis maksimaalses koguses lämmastikku saav variant. Kaaliumisisaldus vähenes kõigi katses olnud variantide mullas. Et kaaliumisisaldus ei väheneks kriitilise piirini, peab mulda viidava kaaliumi kogust suurendama – mahesüsteemis... |

| The aim of this study was to investigate how different farming systems influenced tuber yields and quality (N, NO3−, P, K, Ca, Mg, dry matter and starch concentrations) of potato as well as how potato cultivation within a crop rotation under different farming systems affects soil quality (pH, Ntot, Corg, plant available P, K, Ca and Mg concentrations). Potato (Solanum tuberosum L.) was part of a five crop rotation experiment in which red clover (Trifolium pratense L.), winter wheat (Triticum aestivum L.), peas (Pisum sativum L.), potato and barley (Hordeum vulgare L.) followed each other simultaneously on a same field. Data presented in this paper concerned the first 3 years of the rotation during 2009–2011. The experiment was performed with six different... |

| Mahepõllumajanduses seab saagikusele tihti piiri umbrohtumus, kuivõrd konkureeritakse kultuurtaimedega vee, päikesevalguse ja toitainete pärast ning sageli ollakse vaheperemeesteks ka kahjuritele ning haigustele (Hole jt., 2005). Samas suurendavad umbrohud elurikkust ja toetavad põllukoosluse ökoloogilist talitluskindlust, luues toidubaasi taimekahjustajate looduslikele vaenlastele. Seetõttu tuleb taimekasvatusele kasuks nende mõningane olemasolu põllul, ent liigse konkurentsi vältimiseks tuleb nende arvukust siiski reguleerida, kuid loodushoidlikul moel. Selles on üheks olulisemaks meetmeks läbimõeldult kavandatud külvikord. Kultuuride mitmekesisus parandab kultuurtaimede võimet võidelda kahjurite ja haigustega ja vähendab umbrohtumust (Altieri, 1999;... |

| Maheviljeluses kasutatakse mitmeaastast külvikorda, mis säilitab ja suurendab mulla viljakust ja bioloogilist aktiivsust ning kus kasvatatakse liblikõielisi ja haljasväetistaimi või kasutatakse väetamisel komposteeritud sõnnikut (Mahepõllumajanduse seadus, 2007; Palts ja Vetemaa, 2012). Seega on õhulämmastikku siduvaid ja mügarbaktereid moodustavate liblikõieliste taimede kasvatamine maheviljeluse üheks põhitingimuseks. Liblikõielised taimede kasvatamine soodustab ka teiste toiteelementide (P, K, mikroelemendid) omastamist mullast või orgaanilisest materjalist. Hernes, kui mahekülvikorda hästi sobiv kultuur on vähenõudlik ja kasvutingimuste suhtes leplik taim, mis kasvab hästi keskmistel liivsavi- ja saviliivmuldadel. Ka ei vaja ta teraks kasvatamisel... |

| The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among... |

| Abstract The TILMAN-project aims to develop robust and sustainable arable crop production systems via the introduction of reduced tillage techniques combined with a strategic use of green manures in organic crop rotations, while maintaining and improving soil quality and crop productivity parameters. The adoption of reduced tillage and/or green manures strongly affects nitrogen quantity and availability during the vegetative period and throughout the crop rotation. Specifically, changing soil and water conditions may affect the availability pattern of nitrogen, notably in spring. We present aggregated data of several long- and medium-term European experimental field studies in which green manures including cut-and-carry-fertilizers, and reduced tillage... |
