Sugarcane Yield Response to Furrow-Applied Organic Amendments on Sand Soils

Table 1

Characterization of organic amendments.

Organic material	Loss on; ignition	Moisture; (dry basis)	Dry; density^a				Total applied with selected rates
				Dry basis			226 m^3 ha^−1		56 m^3 ha^−1
				Total N	Total P	Water soluble K	N	P	N	P
	g kg^−1	%	g L^−1	g kg^−1			kg ha^−1
Mill Mud Site 1	357	111	489	11.3	21.4	<0.1	1249	2365	309	586
Mill Mud Site 2	338	131	423	8.8	12.8	<0.1	NA^b	NA	208	303
Compost Site 1	317	88	377	9.9	3.9	<0.1	843	332	209	82
Compost Site 2	412	86	476	7.9	1.6	<0.1	NA	NA	211	43

Dry density was determined by measuring the wet bulk density of each material as applied and also determining moisture content of each material.
^bNA: not applicable. The broadcast rate of 226 m³ ha⁻¹ was not applied at Site 2.
