Soil moisture

This study applies the GRU (Gated Recurrent Unit) model when selecting different values of batch-size, namely 16, 32, and 64, with varying epochs of 20, 50, 100, 150, and 200. The input data comprises observations collected by two GNSS CORS stations from the VNGEONET network, namely HYEN and CTHO, spanning from August 10, 2019, to March 18, 2022.

The literal meaning of Hysteresis is to be lagged behind. In soil system, it is evident that the two soil moisture characteristic curves do not follow the exact same reversible path. As a result a hysteretic behaviour is experienced. Several causes may be attributed like non uniformity of pores, contact angle difference, entrapped air in pore space and the swelling and shrinking property of soil. To predict the hysteretic behaviour, several models defining the character were also suggested like Conceptual models and Empirical models.

Water stress periods are common in rainfed agriculture therefore the activities aimed at conserving the rainwater should be adopted for improving the productivity of dryland crops. The major crops in Vidarbha region of Maharashtra are cotton, soybean and sorghum. It was observed that the drought situation may arise during crop growth period which may result in partial failure of crops. It was therefore felt worthwhile to adopt the proper methods of in-situ moisture conservation so as to partially meet out the adverse effect of water stress in standing crop.

A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:1). On windrow composting, not only the volume of waste was reduced but also produced a crumbly earthy smelling soil-like, compost material.
