Seasol products Trilogy and Seasol + Calcium were applied to a Kale crop following planting at two intervals. Plot trials demonstrated the crop feed quality improved.
Field trials
- One small plot replicated field trial
- Field trial site—Lincoln (New Zealand)
- Eight replicates
- Plot size measured 10m x 2m
Treatment
Two applications of Seasol Trilogy and Seasol + Calcium were made at 10L/ha.
- Application A: Prior to canopy closure on 19 December 2022.
- Application B: After canopy closure on 19 January 2023.
Application 1: 19 December 2022
Application 2: 19 January 2023
Assessment
A fresh weight yield assessment was taken on 8 June 2023, along with leaf samples for foliage analysis on 14 June 2023.
Key Results:
Seasol improved feed quality of NZ Brassica.
Crude protein was higher in Seasol + Calcium (24.5% DM) and Trilogy (23.7% DM) than the control (19.8% DM).
Seasol + Calcium and Trilogy also had slightly higher metabolizable energy, with 13.5 MJ/kg DM and 13.6 MJ/kg DM respectively, compared to the control (13.4 MJ/kg DM).
Both Trilogy and Seasol + Calcium had higher foliage nitrogen levels, with 3.6% and 3.7% N respectively, compared to the control with 3.0% N.
The foliage content of phosphorus, sulphur, zinc, and chloride was also higher in the two treatments compared to the control.
