| Maintaining or enhancing the stock of soil organic carbon (SOC) is a key factor in sustaining the soil resources of the world. The objective of this research was to study the effect of different farming systems (conventional farming with mineral fertilizers and crop specific fertilization vs. organic farming with organic fertilizers (catch crops and composted manure)) under the same 5-crop rotation (red clover, winter wheat, pea, potato, barley undersown with red clover) system on the SOC stock and the stability of SOC. The second aim was to quantify plant C inputs to the soil and to identify the relationship between C sequestration rate and C input. Data presented in this paper concerned the first rotation during 2008–2012. The main factors were farming... |

| Kartuli kuivlaiksust (Alternaria solani, A. alternata) on seni Eestis peetud suurt kahju põhjustavaks kartulihaiguseks. Viimastel aastatel on kuivlaiksus osutunud suureks probleemiks Eesti kartulipõldudel, seda eriti just vastuvõtlikel sortidel. Kuumadel keskmise niiskusega kasvuaastatel on kuivlaiksusele vastuvõtlikel sortidel vaja tavaviljeluses teostada keemilist tõrjet, kuna haigus hävitab enneaegselt kartuli lehestiku, sageli enne veel kui lehemädanik lööbida jõuab. Kuivõrd maheviljelus välistab keemilise tõrje, siis tuleb leida kasvatustehnoloogilisi võtteid ning kasutada võimalikult haigusekindlaid sorte. Uurimustöö eesmärgiks oli selgitada, kuidas erinevad maheviljeluse tehnoloogiad mõjutavad kartuli kuivlaiksuse arengut haigusele soodsal... |

| Jätkusuutlikuks maheviljeluseks on oluline arendada viljelussüsteeme, mis tagaksid elurikkuse suurenemise, mullaviljakuse paranemise ja hea ning kvaliteetse saagi. Selles mängib keskset rolli liblikõielisi kultuure sisaldav ja taimetoitainete tasakaalu säilitav kohalikesse oludesse sobiv külvikord. Taimetoitainetega paremaks varustatuseks saab külvikorras kasutada veel vahekultuure, komposte või sõnnikut. Nende lagunemisel muutuvad toitained taimedele kättesaadavaks aeglasemalt ja ühtlasemalt, kindlustades nii külvikorras järgnevate kultuuride stabiilse varustatuse lämmastikuga. Käesoleva uurimuse eesmärk oli selgitada odra ja nisu saagikus ning saagi kvaliteet nende kasvatamisel viieväljases külvikorras kolmes eri maheviljelussüsteemis, mis erinesid... |

| Kartul on üheks armastatumaiks kultuuriks nii meil kui maailmas. Teda on läbi aegade peetud teiseks "leivaks" ning tänapäeval ei kujutaks meist keegi ette toidulauda, kust puuduks kartul (Eremeev jt., 2012). Mahepõllumajanduslikult kasvatatav kartulipind on Eestis pidevalt suurenenud. Samas ei ole seni veel piisavalt andmeid selle kohta, kas põhiliselt vaid mulla toitainevarudel ja haljasväetistaimedel baseeruv majandamine on piisavalt jätkusuutlik. Kas ilma sõnnikuta külvikordades – paljudes mahetaludes ju loomakasvatus puudub – võib toimuda mulla väljakurnamine (Järvan jt., 2014)? Käesoleva töö eesmärgiks oli uurida kuidas erinevate maheviljelusviisidega kartuli kasvatamine mõjutab mulla toitainete sisaldust. |

| 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... |

| In a field experiment based on a five-year crop rotation (pea, potato, barley undersown with red clover, red clover and winter wheat), several soil parameters, porosity, number and biomass of earthworms, total nitrogen, organic carbon, percentage of water stable aggregates and enzymatic activity, were studied during 2013 and 2014, the first and second year, respectively, since the first rotation concluded. This rotation was managed under three organic farming systems: Organic 0 (control), Organic I (with winter cover crops lately incorporated into the soil as green manure) and Organic II (with the same cover crops plus a yearly amendment of 40 t ha−1 of cattle manure). Crop rotation had a yearly positive effect on the soil bulk density, and enhanced the... |

| Kartuli (Solanum tuberosum L.) hõbekärn (Helminthosporium solani Durieu, Mont) on seenhaigus, mis viimastel aastatel on osutunud tootmises äärmiselt problemaatiliseks. Haigustekitaja nakatab valmivaid mugulaid juba mullas, kuid eoste kaudu levib haigus hoidlas jõudsalt edasi, mistõttu peetakse hõbekärna ka säilitushaiguseks. Patogeen tungib mugulasse läbi loomulike avade siis, kui mugulad on saavutanud juba oma suuruse ja massi, kuid toimub veel koore kinnistumine. Seetõttu on vajalik mugulad põllult võimalikult ruttu koristada. Hõbekärna nakatunud mugulate koore pinnale tekivad pruunikashallid laigud. Kui mugulad puutuvad kokku veega ilmneb nakatunud kohal iseloomulik hõbe-metalne läige. Eriti hästi ongi haigust näha just pestud mugulate pinnalt.... |

| 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... |

| In organic agriculture, soil fertility is essential for harvesting high quality crop yields. Plant nutrient cycles should be kept short and as closed as possible. Therefore, it is important to have sustainable growing systems that have rotations with appropriate crops and cover crops. In organic farming green manures and cattle manure are also used to ensure fertile and biologically active soil and to enhance biodiversity. Green manures offer supporting services, such as nutrient cycling, promotion of beneficial insects for pest control and soil formation. Also the catch crops on winter period are essential to reduce nutrient leaching (Stark and Porter, 2005). Growing system does not only influence the soil fertility, but through that also the quality... |

| Since 2008, a 5-year crop rotation experiment (winter wheat, pea, potato, barley undersown with red clover, and red clover) has been run in Tartu, Estonia, to evaluate the changes in soil chemical parameters under four fertilizer managements: (1) unfertilized conventional plots (conventional I), (2) conventional plots with addition of mineral fertilizers (conventional II), (3) organic plots with cover crops during the winter period (organic I), and (4) organic plots with the same cover crops plus a yearly amendment of 40 t ha–1 of cattle manure (organic II). After the first rotation, results showed significant differences (P < 0.05) in soil acidity dependent on the system with mean values ranging between 5.67 (conventional II) and 6.10 (organic II).

| Kartul on üheks armastatumaiks kultuuriks nii meil kui maailmas. Teda on läbi aegade peetud teiseks "leivaks" ning tänapäeval ei kujutaks meist keegi ette oma toidulauda, kust puuduks kartul (Eremeev jt., 2012). Hea eelkultuurina teraviljadele sobib ta hästi ka päikesepinnalistesse külvikordadesse. Kartulit saab edukalt kasvatada maheviljeluslikus suletud tsükliga tootmisüksustes, kus on võimalik kasutada loomapidamisest tekkivad sõnnikut (Järvan ja Edesi, 2012). Maheviljeluslikus külvikorras on oluline osa vahekultuuride kasvatamisel. Põhikultuuride kasvatamise vahepealsel ajal vahekultuurid kaitsevad ja rikastavad mulda toitainetega ning suruvad alla umbrohtumust. Vahekultuure ei kasvatata müügikasu eesmärgil, vaid sissekündmisel muutub see... |

| 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... |
