Reasonable deep application of sheep manure fertilizer to alleviate soil acidification to improve tea yield and quality.

In this study, it was found ( Figure 3A ) that sheep manure fertilizer was beneficial to root activity and total root nitrogen content of tea trees, and the two indexes generally showed an increasing trend with the extension of sheep manure fertilization time (2018-2022).

Secondly, as the application depth of sheep manure increased (from 0 cm to 100 cm), soil pH, tea yield, and amino acid and theanine content in tea leaves showed a trend of increasing and then decreasing, all reaching maximum values at the application depth of 70 cm.

Secondly, soil nitrate nitrogen content, nitrifying bacteria number and nitrification intensity showed a decreasing trend overall with the extension of fertilizer application time (2018 to 2022) ( Figure 5B ).
