Problem hydromorphic soils in north-east Thailand. 1. Environment and soil morphology.

open access: yesNetherlands Journal of Agricultural Science, 1977
The Roi Et soil, a Gleyic Acrisol (FAO, 1974) is one of the main soils on the extensive seasonally wet, low terrace in north-east Thailand. The soil looks poor and produces traditionally low yields of one paddy rice crop/year. With fertilizers and dry-season irrigation, problems of water-logging, surface salinity and acidity caused poor germination and

Arguments for and against self and non-self root recognition in plants [PDF]

open access: yes, 2014
Root–root interaction research gained more and more attention over the past few years. Roots are pivotal for plant survival because they ensure uptake of water and nutrients.

Root traits of different wheat cultivars influence soil structure: an X-ray computed tomography and root morphology study

open access: yesGeoderma
Plant roots play a fundamental role in maintaining soil health. Although a broad range of root traits have been reported, few studies have attempted to link root morphology with soil structure.

Characterising the tumour morphological response to therapeutic intervention:an ex vivo model [PDF]

open access: yes, 2012
In cancer, morphological assessment of histological tissue samples is a fundamental part of both diagnosis and prognosis. Image analysis offers opportunities to support that assessment through quantitative metrics of morphology.

Relação da granulometria do solo e morfologia do saprolito com a infiltração de água em Neossolos Regolíticos do rebordo do Planalto do Rio Grande do Sul Relationship between soil size particle distribution and saprolite morphology with water infiltration in Neossolos Regolíticos (Regossols) in the Rio Grande do Sul Plateau edge

open access: yesCiência Rural, 2009
Os Neossolos Regolíticos apresentam baixo potencial de uso devido a sua pequena profundidade efetiva, à presença de pedregosidade/rochosidade, ao contato lítico próximo à superfície e à ocorrência frequente em terrenos declivosos.

Factors affecting the soil binding capacity of the root systems of some populus and salix clones : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Botany at Massey University [PDF]

open access: yes, 1973
Man-induced changes in the vegetation of New Zealand over the last century have resulted in large areas of actively eroding land, both in the steeplands which still retain a form of forest cover, and in large areas of moderate to steep hill country ...

Quantitative characterization of pore structure of several biochars with 3D imaging

open access: yes, 2017
Pore space characteristics of biochars may vary depending on the used raw material and processing technology. Pore structure has significant effects on the water retention properties of biochar amended soils.
