EFFECT OF SOLARIZATION AND AMENDMENTS ON THE PINE DAMPING OFF AND SOIL PROPERTIES
The effects of solarization using polyethylene mulching for 45 and 60 days combined with soil amendments of chicken manures (CM), mixed fungicides of metalayxl 2g and benlate 1.5g L-1 (Met.&Ben.), biocontrol agent of Trichoderma harzianum (T.h.). and NPK fertilizers 180kg N h-1 on the pine damp...

| description | The effects of solarization using polyethylene mulching for 45 and 60 days combined with soil amendments of chicken manures (CM), mixed fungicides of metalayxl 2g and benlate 1.5g L-1 (Met.&Ben.), biocontrol agent of Trichoderma harzianum (T.h.). and NPK fertilizers 180kg N h-1 on the pine damping off in Malta nursery had been ascertained in Summer 2008. Pre-emergence damping-off on the pine seedlings grown in dry soil was 83.33% with disease severity of 60%, while solar heating for 45 days reduced the disease occurrence to 45% and its severity 11.67%. Amendments of CM., Met. & Ben., and T.h. after 60 days controlled disease to a lesser extent than other treatments. Obvious increasing of organic matter, 2.63%, NH+4– N 0.08 g N and NO–3 – N 0.05 g N 100g-1 soil in addition to soluble nutrients of P 8.91 mg and K 0.035 Meq K 100g-1 soil was recorded in the mulching soil. At the same time composted heating plots decreased C/N ratio to relatively optimal levels of 15.75 and 18.59 after both of solar periods, alkaline soil pH (8.41 – 9.56) did not incongruous with the efficiency of biocontrol T.h. in the decomposition of organic matter and availability of the most nutrients even in the solarized soil. |
