Ecological Processes

Table 4 A summary of the effects of agriculture on the downstream riverine and estuarine water properties. When most minerals (e.g., Na⁺, Mg²⁺, Cl⁻, K⁺, Ca²⁺) increased, they were collectively described as EC increased. The arrows before the water properties indicate that the subsequent water properties increased (↑), decreased (↓), or did not change (→). See the list of abbreviations for the water properties
