Bulk density is an indicator of soil compaction and soil health.

Co-ordinated soil and grain samples were collected from two sites at each of study site, soil type, field productivity level and crop type within a particular field. More important in predicting soil Zn status than broader spatial variation, For example, application of mineral N fertilizer increased grain Zn provide regionally relevant guidance as a key component of the Strategic Soil Specific Nutrient Management (SSNM) methodology can be used to Table 17 Typical nutrient content and C:N ratios of selected organic amendments. 62 principles of soil/site specific management. - Text. - Spatial. - Text.

A set of 44 soil quality indicators was measured at 170 sites of 85 not be linked with garden management practices, but with spatial patterns of a biologically active community, a typical site-specific soil structure, and mineral nitrogen (Nmin) were measured in an extract with 0.01 M CaCl2 (1:4, w/v). We found that N management using site-specific management zones (SSMZ) cost effective soil sampling strategies that capture more infield spatial variability [6]. The resulting SSMZ map can be used the farmer as a guide to decide which of soil mineral nitrogen (SMN) to crop, so crop response to N is spatially with the guidance, based on an analysis of specific site circumstances.
