Agricultural water

Microplastics are regarded as an emerging threat to water and other environments. The increasing use of plastics in agricultural cultivation has led to higher risks and more dangerous pollution of agricultural water. However, microplastics in agricultural water in Vietnam have neither been studied nor documented in any publication.

Biofertilisers are defined in this application as microbial inoculants, isolated from soil or the rhizosphere of plants, assisting the mobilisation of soil nutrients such as N and P and others in the plant rhizosphere and thus promoting the growth rate and yield of plants. Successful biofertilisers can contribute to increases in food production in a highly sustainable manner, with economic and environmental advantages.
