Key inputs for the production and distribution of "frac sand" include land, labor and transportation networks. We study how the recent boom in the Upper Midwest has impacted agriculture and rural prosperity.Emerging evidence suggests there are likely significant negative local externalities from the recent US oil and gas drilling boom, but few studies examine the impacts on agriculture and
The Lecturer said a recent study has shown that the use of arable lands for construction and sand winning purposes has become a major concern among farmers in Akyemansa and Ayensuono districts in recent times, with the situation contributing to climate change as well as negative effects on biodiversity conservation.

Introduction. Soil Fertility Initiatives in Malawi. Declining soil fertility ranks high among the factors limiting smallholder arable crop production in Malawi (Snapp et al., 1998).This problem has been caused by diminishing land holding sizes as a result of the ever-increasing population growth rate currently at 3.2%.

This Factsheet looks at the causes and effects of water, wind and tillage erosion on agricultural land. Figure 1. The erosive force of water from concentrated surface water runoff. Water Erosion. The widespread occurrence of water erosion combined with the severity of on-site and off-site impacts have made water erosion the focus of soil
Oct 01, 2018· Crop rotation had a positive effect on SOM content and yield; rotation with ley very positively influenced earthworms’ numbers. Overall, crop rotation had little impact on soil pH and aggregate stability − depending on the type of intercrop; alternatively, rotation of arable crops only resulted in adverse effects.
Jan 01, 2018· The mean area of agricultural land limed for the 10 years prior to 2016 was: 8.6% for arable crops, 6.1% for temporary grassland (< 5 years) and 3.2% for permanent grassland (> 5 years) (DEFRA, 2016). These statistics suggest that liming is becoming less common and the implications of this decline in liming need to be understood.

Dec 10, 2016· Rural farmers demonstrate adequate knowledge of the occurrence of land degradation and its causes (Table 1). The main signs of land degradation mentioned by respondents were increased bare lands, presence of erosion gullies and declining soil fertility, and these were believed to be caused by soil erosion, bush burning, over cultivation, cutting of trees, illegal mining and sand winning.
