Cattle Manure Disposal on Potato Growing Fields in Conditions of the Southern Forest-Steppe of the Bashkortostan Republic

Abstract

Higher yields of environmentally friendly potato require more organic fertilizers and irrigation. The most common organic fertilizer is cattle manure. The research goal is to study the effect of irrigation and high rates of cattle manure used in conditions of the southern forest-steppe of the Bashkortostan Republic on the yield and quality of potato tubers. The conducted study demonstrates increased potato tuber growth from 0.12 to 0.72 kg/plant and 0.30 to 0.79 kg/plant with a higher rate of cattle manure (120 t/ha) under rainfed and irrigation conditions, respectively. Cattle manure disposal is one of the most acute issues in terms of environmental conservation. It is a great concern in farming practice worldwide that requires the scientifically-proven use of farmyard manure. To get consistently high yields of crops and maintain soil fertility becomes possible when taking into account local agro-meteorological and soil conditions. The optimal rates of cattle manure for potatoes cultivated on leached chernozem in the southern forest-steppe of the Republic of Bashkortostan under irrigation and rainfed conditions were found. Potato growing at different rates of cattle manure application has been studied. There is an economic assessment of efficiency to apply different rates of manure.

The role of soil microorganisms in enhancing phosphorus availability from dairy processing waste in grasslands

“…The lack of homogeneity in available P testing across Europe makes it even more complicated to give estimates on P fertilization rates. Using different soil P tests under fertilization with DPW or recycled materials ("cocktails") poses another challenge to the estimation of plant available P, as different reagents have different affinities for specific forms of P. It has been found, for instance, that the Morgan's P (Garbouchev, 1980;Kewai et al, 1997;Fernandes et al, 2000;Lončarić et al, 2006;Ailincăi et al, 2008;Komljenović et al, 2010;Jordan-Meille et al, 2012;Khristenko and Ivanova, 2012;Guðmundsson et al, 2014;Iatrou et al, 2014;Jordanoska et al, 2014;Manea et al, 2016;Salković et al, 2018;Shafeeva et al, 2021;Janković et al, 2023;Khomenko et al, 2023b) test (commonly used in Ireland) results in an overestimation of plant available P from limed DPW materials (Ashekuzzaman et al, 2021). Similarly, when analysing plant available P from a range of P forms in chapter 3, I also detected an overestimation of plant available P from hydroxyapatite when using the Joret-Hébert method (data not shown).…”
