Experimental Design
Design (short description): 
The main experimental treatments are: (i) green cane harvested with retention of a trash blanket (100% cover) (T), (ii) burning prior to harvest with tops left scattered on plots (67% cover) (Bt) and (iii) burning prior to harvest with all tops raked of plots (Bto). The treatments are either (a) unfertilized (Fo) or (b) fertiilized annually with 140 kg N/ha, 20 kg P/ha and 140 kg K/ha (F). The experiment is replicated four times in a randomized split-plot design.

Seven decade South African Vertisol-sugar cane study

Welcome aboard Rianto!!
This is excellent, a Vertisol supporting sugar cane.
I look forward to future communication.
