The impacts
Reducing over-fertilisation is crucial for minimising environmental degradation . Excessive fertiliser use can lead to nutrient runoff , which contaminates water bodies and disrupts ecosystems . By using SoilProp ©, farmers can significantly reduce the environmental impact of their agricultural practices , promoting more sustainable and ecofriendly farming methods .
SoilProp © is designed to rapidly provide accurate soil information , significantly improving efficiency compared to conventional methods . For an area of 100 hectares , SoilProp © can deliver results within three to four days , whereas traditional soil fertility assessment methods typically take two to four weeks . These traditional methods are labour-intensive , costly , and timeconsuming , requiring substantial human resources and financial investment .
By implementing the SoilProp © system , farmers can achieve notable economic benefits . Crops cultivated using this system have shown an increase in yield by up to 26 %, while fertiliser costs can be reduced by up to 50 %. This dual advantage not only boosts farmers ’ income but also enhances overall agricultural productivity . Moreover , by optimising fertiliser use , the system helps farmers apply the precise amount of nutrients needed , reducing waste and ensuring that crops receive optimal nourishment for growth .
In addition to the direct benefits to farmers , the system also offers significant advantages for Government agricultural policies . Fertiliser subsidies constitute a major portion of Government support for farmers . By enabling more efficient and effective fertiliser use , SoilProp © allows for better control and a potential reduction of these subsidies , leading to substantial savings in public expenditure .
Furthermore , the system plays a critical role in environmental conservation . By minimising the overuse of chemical fertilisers , SoilProp © reduces nutrient runoff into water bodies , thereby reducing pollution and mitigating the negative impact on ecosystems . This technology supports sustainable farming practices , promoting a balance between agricultural productivity and environmental stewardship .
