RETURN ON INVESTMENT VITICULTURE
1 / 9ページ

The following Return on Investment (ROI) is based on 40 acre vineyards. Each example shows the cost of application prior to using the Soil Information System™ (SIS) solution. These inputs were typically applied at a flat rate across all 40 acres. Once SIS determined different zones (e.g. A, B, C,...), application of inputs varied which resulted in cost savings. Not only did this result in higher profits, it also helped reduce the environmental impact. Whether utilizing these tools to apply the correct amount of water to the plant, drive variable rate fertility applications, determine root stock selection, or carry out tillage practices, SIS can immediately impact your return on invest
