2. Agroforestry - Wikipedia

   en.wikipedia.org/wiki/Agroforestry

   In one example, a ten-year experiment in Malawi showed that, by using the fertilizer tree Gliricidia (G. sepium) on land on which no mineral fertilizer was applied, maize/corn yields averaged 3.3 metric tons per hectare (1.5 short ton/acre) as compared to 1 metric ton per hectare (0.45 short ton/acre) in plots without fertilizer trees or ...

   Oct. 5—MORGANTOWN — In light of the ongoing drought, two WVU Extension experts have offered some insight and advice on how drought can affect livestock and wildlife. Darin Matlick, a ...

4. Controlled-release fertiliser - Wikipedia

   en.wikipedia.org/wiki/Controlled-release_fertiliser

   Slow- or controlled-release fertilizer: A fertilizer containing a plant nutrient in a form which delays its availability for plant uptake and use after application, or which extends its availability to the plant significantly longer than a reference ‘rapidly available nutrient fertilizer’ such as ammonium nitrate or urea, ammonium phosphate ...

5. Park Grass Experiment - Wikipedia

   en.wikipedia.org/wiki/Park_Grass_Experiment

   The Park Grass Experiment is a biological study originally set up to test the effect of fertilizers and manures on hay yields.The scientific experiment is located at the Rothamsted Research in the English county of Hertfordshire, and is notable as one of the longest-running experiments of modern science, as it was initiated in 1856 and has been continually monitored ever since.

   FDP involves "briquetting" nitrogen fertilizer by compacting prilled fertilizer into 1-3 gram briquettes. The briquettes (either urea- or NPK-based) are then placed in a plant's root zone, as opposed to the traditional application method of broadcasting. Trials have shown that FDP and UDP (when only urea is used) can increase crop production up ...

7. Crop rotation - Wikipedia

   en.wikipedia.org/wiki/Crop_rotation

   In an opportunity cropping system, crops are grown when soil water is adequate and there is a reliable sowing window. This form of cropping system is likely to produce better soil cover than a rigid crop rotation because crops are only sown under optimal conditions, whereas rigid systems are not necessarily sown in the best conditions available ...

8. Organic fertilizer - Wikipedia

   en.wikipedia.org/wiki/Organic_fertilizer

   Organic fertilizer nutrient content, solubility, and nutrient release rates are typically much lower than mineral (inorganic) fertilizers. [ 38 ] [ 39 ] A University of North Carolina study found that potential mineralizable nitrogen (PMN) in the soil was 182–285% higher in organic mulched systems than in the synthetics control.

9. CO2 fertilization effect - Wikipedia

   en.wikipedia.org/wiki/CO2_fertilization_effect

   Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems).
