Assessment of the Effectiveness of Ectomycorrhizal Inocula to Promote Growth and Root Ectomycorrhizal Colonization in Pinus patula Seedlings Using the Most Probable Number Technique

Applied and Environmental Soil Science, Volume 2014, Issue 1, 2014., 2014
The aim of this study was to evaluate the response of Pinus patula seedlings to two inocula types: soil from a Pinus plantation (ES) and an in vitro produced inoculum (EM). The most probable number method (MPN) was used to quantify ectomycorrhizal propagule density (EPD) in both inocula in a 7‐order dilution series ranging from 100 (undiluted inoculum)

Quantification nitrifying bacteria in a Typic melanudands soil under three land use conditions in Pasto, Nariño, Colombia

, 2021
Abstract The study was conducted in Pasto, Nariño, Colombia, to estimate the amount of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in three land uses (forest, traditional pasture, and silvopastoral system) at two depths We used a completely randomized design (CRD) with six treatments and three repetitions, resulting in 18 ...

Critical roles of short‐range‐order minerals in shaping soil water retention curves in volcanic regions

Vadose Zone Journal, Volume 24, Issue 5, September/October 2025.
Abstract Predicting water retention is difficult for highly aggregated volcanic soils (Andisols) with heterogeneous pore size distribution. This paper aimed to examine how andic materials influence soil water retention based on soil composition. We compiled the data of water retention in the soils from literature with physicochemical properties and ...

Retention and availability of phosphorus associated with organic matter in a typic melanudands of cauca department, colombia

, 2013
The effect of organic matter on retention and Phosphorus (P) availability in a Typic Melanudands cultivated coffee (Coffea arabica) and guamo (Inga spuria), was evaluated by isotherms from the Langmuir equation using linearized by Scatchard and using the method proposed by Fox and Kamprath.
