  1. 1. Nitrogen fixation in wheat (Triticum aestivum) : effect of Azotobacter salinestris CECT 9690 on N-accumulation

    University essay from SLU/Dept. of Soil and Environment

    Author : John Pålsson; [2023]
    Keywords : Biostimulants; Vixeran; N-uptake; N-concentration; yield; cereals;

    Abstract : Biostimulants are products that can improve nutrient availability, nutrient uptake, nutrient use efficiency and tolerance to abiotic stress with the aim to increase plant growth and yield. During the last decades, the interest in, and market for biostimulants has grown and is expected to have a large compound annual growth rate. READ MORE

  3. 2. Hur påverkas daggmaskar av markpackning?

    University essay from SLU/Dept. of Ecology

    Author : Kifilo Oumar; [2022]
    Keywords : daggmask; markpackning; vetesort; anecisk; endogeisk; epigeisk;

    Abstract : Det här arbetet gjordes med ett färdigställt dataset över antal och biomassa av daggmaskar från ett fältförsök med markpackning. Målet med arbetet har varit att undersöka om daggmaskarna har påverkats negativt av markpackning, i kombination med andra abiotiska faktorer som förekommer under varje växtsäsong. READ MORE

  4. 3. Tillväxteffekter för tall 33 år efter konventionell gallring och gödsling

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Gustav Nord; [2018]
    Keywords : gallring; gödsling; långsiktig; tillväxt; thinning; fertilization; long-term; growth;

    Abstract : Gallring och gödsling är i Sverige två vanliga och viktiga skogskötselåtgärder. Gallring är den arealsmässig vanligaste skogsbruksåtgärden. Skogsgödsling däremot har varierat i omfattning de senaste årtiondena och är idag inte särskilt omfattande. READ MORE

  5. 4. Optimering av reducerad bearbetning : högre skörd till lägre kostnad

    University essay from SLU/Dept. of Soil and Environment

    Author : Nils Wiklund; [2013]
    Keywords : jordbearbetning; reducerad bearbetning; infiltration; dragkraftsmätning; penetrometer;

    Abstract : Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome.

  6. 5. The effect of push-pull management and different fertilization strategies on maize crop yield in central Kenya

    University essay from SLU/Swedish Biodiversity Centre

    Author : Peterson Newton Muchiri Njeru; [2009]
    Keywords : Soil fertility; central Kenya highlands; manure; fodders; fertilizer; smallholder farmers; ‘push-pull’; monoculture; Kenya;

    Abstract : The high population pressure in central Kenya has lead to continuous cultivation with minimal application of nutrient, resulting in nutrient depletion. A study was conducted to determine the effect of 'Push-pull' (intercropping maize with desmodium and napier grass) strategy management and nitrogen application on maize grain yield and soil fertility on smallholder farmer’s fields in three districts of central Kenya highlands.
