احصل على السعر01/06/2020 The benefits of sugar beet in the arable rotation Sugar beet is an essential crop for many farmers and often plays a vital role in soil and crop health in the arable farm rotation. Sugar beet acts as a ‘break’ crop in the rotation, and this means it provides a break or a rest from the more intensively farmed cereal crops that dominate most arable rotations.
احصل على السعرSugar beet is very sensitive to pH in the soil and will only produce a high yield when grown in soil with a neutral to high pH. The pH depends on the soil type: sandy loam to clay soils the pH has to be 6.5 to 7. sandy soils the preferred pH is 5.5 6.0. soils high in organic matter the preferred pH is

احصل على السعرSite-specific management of N (NSSM) is an attractive and intuitive approach to increasing N fertilizer use efficiency (NUE) of agricultural systems by adjusting fertilizer rates to the soil characteristics. The objective of this study is to assess: whether delineating of management zone (MZ) within fields improves NUE in wheat (.
