Growing seedlings of pinus sibirica du tour with a closed root system on experimental substrates

The issue of growing Pinus sibirica Du Tour seedlings with a closed root system on experimental mixtures based on peat has been studied. The main component of the substrate was peat of local origin, mined in the Kozulsky district of the Krasnoyarsk Krai. Peat was mixed with sawdust, vermiculite, and perlite in different proportions. In a number of experimental mixtures, coconut substrate was used as the main component instead of peat. Peat produced by VELTORF LLC was used as a control substrate according to recipe No. 19c/1. 

Conducted studies of the growth of Pinus sibirica Du Tour seedlings grown with a closed root system in cassettes with different compositions of substrates allowed us to draw a number of conclusions: when using clean peat, it is advisable to use fertilizers; Coconut substrate can serve as a complete replacement for peat substrates, if mixed with vermiculite in a 50/50% ratio; It makes sense to pay attention to peats of local origin to reduce costs.
