Reply to SAP analysis on tomatoes
Thanks Andre for your thoughts. I’ll attach my last soil analysis. My pH is a bit on the high side 6.9. TEC 10.2. I have addressed the problem with Mo, Co and B. My soil is rather on the heavy/clay side, but not too heavy, and the site is also pretty wet in winter, but rarely with standing water. I have also applied quite a bit of sulphur…

There is no Cl coming from fertilizer (farmer does not use KCl), but a lot of Cl is coming with the irrigation water…

Hallo Ido in a recent online course Novacrop confirmed that Cl limit N, S and P. They use Cl to limit N if needed.
Check anion balance. You could consider to use rain water at least for foliar. Cl is very volatile u could consider to aereate water for foliar with a pump also according E.Ingham humic acids help to buffer in some way Cl. Also… Read more - View more comments

I had to look up what slaters were. Different name in the states! Anyhow I’ve had this problem before with entire plantings of young plants, mostly beet, were completely devoured and I found it was that I had a rather thick mulch layer around the plantings and they were prolific under the mulch as they should be. I’m not certain it’s a…

thanks Rowan,
I agree with you. Super wet, things not balanced, favored a proliferation of slaters. I believe things have improved overall in those paddocks in last 3 years, so while a “setback” this season should indicate we are on the right path.
