Circular agriculture is the agricultural production process in a closed cycle, which the waste and by-products of one process are the input to the other production process, through the application of technical advances and biotechnology. Thus, agricultural production will exploit and use resources economically and efficiently, minimizing post-harvest losses, especially reducing and eliminating wastes that pollute the environment, protecting ecosystems and human health. The objective of this study was to evaluate the effects of several types of available materials such as rice husk ash, coconut coir, canna residue, peat, chicken droppings, pig feces and cow feces, which can be found freely in Vietnam. The experiment was arranged in a completely randomized block design consisting of 5 reatments and 3 replicates. Klasmann was the control treatment for this experiment. The results of implementation in 2022 showed that treatment 1 (CT1) with a mixture of 25% RHA + 25% CC + 25% CR + 25% PF (amount by volume) gave the values of the characteristics of substrate as well as the parameters of H'mong cucumber seedlings were the best.Nông nghiệp tuần hoàn là quy trình sản xuất nông nghiệp theo chu trình khép kín, trong đó phế thải, phụ phẩm của quy trình này là đầu vào của quy trình sản xuất kia thông qua việc ứng dụng những tiến bộ khoa học, kỹ thuật.
